Adding my own positive review of stephen and iaperformance.

I'm in the process of swapping a jdm avcs motor into my bug eye. Dumb me forgot that the valve cover gaskets were different. up against a deadline, I ordered the gaskets from stephen yesterday, and they showed up today at 10:30 as promised. I was definately not in a good mood while on the phone (sorry bud!) but he didn't take anything personally and got me squared away.

motor is now together ready to be put back in.

A very positive E-tune experience! This was my second car tuned by IAperformance. The first was a pro tune at the old shop in Arizona and I have to say the E-tune performance results are similar. Stephen walked me through the process and completed the E-tune after six revisions. Overall, great customer service and I recommend IAperformance to anyone.

Default Broke the mold; set the standard

With my recent experience with IA Performance (“IAP”) there are a few descriptors that I rarely hand out to a company these days; some that come to mind are: exceptional, friendly, helpful, and customer-service centric.

I accidentally ordered the wrong size speaker adapter ring set. I ordered the 6.5” ring set, but it turns out I needed to purchase the 5.25” ring set instead. I contacted Stephen at IAP after realizing my error while attempting to test fit the speakers to the adapter rings. Stephen asked me to send him some pictures of what I was describing; I also sent him pictures of the speaker. Aside from promptly returning my e-mails, he was patiently working with me for a few days, aiding me in which measurements to take to make sure that the 5.25” adapter ring set would indeed work for my speakers. After everything was said and done he’s confident that they will.

Here’s the kicker. Before any of this troubleshooting began, I had offered to send back my incorrect 6.5” adapter ring set for a direct exchange for the 5.25” adapter ring set with each of us covering our respective shipping and not worrying about the price difference. To my surprise, Stephen sent out the 5.25” adapter ring set the very next day and told me to keep the 6.5” adapter ring set and not to worry about sending it back. He also wanted me to keep the hardware from the incorrect kit as it is interchangeable between the two.

IAP has rightfully earned any future business with me and will be considered among a few of the top vendors I hold in high regard. I’m thankful that there are companies out there that take care of their customers the way that IAP does. Thanks for working with me, Stephen. The new adapter ring set arrives today, thanks to the prompt priority 2 day shipping; I can’t wait to get these Focal speakers mounted and installed.

Stephen does it again!! Here's my positive e-tuning experience.

I actually found IAPerformance thru the "authorized e-turners" list provided by Cobb's official website. I emailed a total of 5 tuners who were in the list. Stephen was the ONLY one who replied within minutes of my emails being sent. I had no prior experience with e-tuning or personally knew anyone who had done it. Stephen was extremely helpful. He took the time to answer ALL my questions related and unrelated to the e-tune before I even decided to thru with it.

Stephen delivered what was promised:

Our stage 2 map will deliver 2 items over a OTS Cobb map:
1) better mid range power and smoother power band
2) custom tailored to your specific car unlike a generic map which doesn't take into account for your exact climate, fuel, and driving type

As for emissions, our maps are the same as the COBB units for emissions. Often, emissions are failed due to aftermarket down pipes failing to meet visual inspection or simply too many particles of emission are let through. Our map should not have a check engine light for any stage 2 items.

[email protected]
My STI is far more responsive now than ever before. Now it accelerates quicker at lower RPMs and the acceleration is smooth compared to Cobb's stage 2 map.

If you have a stage 2 and using Cobb Stage 2 map, you are missing out if you're not running a map from Stephen and IAPerformance!!

Thanks Stephen!

Just swapped in a JDM ej205 with avcs. Utilizing the IA valve cover gaskets and wiring kit and a tune from Stephen.

Even though it took over a month due to my busy schedule and dealing with multiple hardware issues with the car Stephen was patient and helpful. The final tune is exactly what I was looking for.

I just got the IA Performance speaker adapters. Picked up an 02 WRX and the front speakers were blown. Got some Alpines from a buddy and knew there would be a depth issue. Speakers fit flawlessly with the adapters. Still have some spacers left (they provide 4 adapters at two different thicknesses that can be stacked if needed) that I intend to use on the rear door to help modify to fit 6.5" coaxial speakers. Hardware included was adequate and worked well.

Positive experience, good product. Thanks!

Great ETuning Service!! My car was running really bad with an OTS map. After the IA performance tune, the car runs great now. I can't say enough about the service Stephen provided. At the beginning the car had issues with fueling and Stephen had no problems waiting for me to fix the car to continue the tuning process. I will definitely use them again and recommend to anybody. Thanks again Stephen and IA for the great service!!!!

Default Tuning experience

I have no words on how great the experience was from stephen with my tuning. He answered all of my questions and stuck through my crappy decision making (which injectors to use, if i should go internal or external, keep my MBC or go EBC). Absolutely perfect experience and will definitely go to him and iA again for anything! If I could give more than 5 stars, i totally would! Thank you very much Stephen and iA, awesome awesome awesome!!

It's been more than a decade since I first became a customer of IAP. From back then till now the service and quality hasn't lapsed. We recently renewed our business relationship again when I needed to source a connector for my IACV which lead me to further invest and get an engine harness instead for the long run. Having a car for more than 15 years mean connectors and other things get old as well. I fully recommend IAP a and will continue to do so in the future. Thanks again for the awesome service Stephen!

Stephen recently did the e-tune on my EJ207 swapped 04 wrx. I cannot say eough about his professionalism and thoroughness in my tune. We went through about 8 revisions to get it dialed in perfectly. He was very prompt in returning emails and sending new maps once i completed the necessary logs. I will definitely be doing business with them again soon

Just finished the etune on my v7 sti swapped wrx. Stephen reeeally knows his stuff and was very patient while i was working out mechanical gremlins. It actually took 13 !!!! revisions, mostly because I had both an undetected fuel leak, and post maf boost leak.

Very very satisfied customer. IAP also ships very quickly and even shipped me some items and didnt even charge me until they were received.

Huge thanks!!!

IA Tuning thumbs up, Stephen Clark runs his business with the kind of work ethic that is no longer so easy to find. The guy knows his stuff and is generous sharing his knowledge on our community. Stephen e tuned my jdm ej207 and my jdm ej205, he demonstrated extreme patience while I was learning the process and was extremely helpful helping fix issues with my setup. I run his AVCS wire kit on both my cars and has earned my business for other parts, everything always arrived quickly but more importantly, has earned my trust. I highly recommend Stephens Clark's business and tuning capability.

Default Tune for 2015 WRX

I recently finished another tune with IATuning and Stephan Clark for my 2015 wrx. Mod list, Cobb intake, catless DP and axel backs on 93. I have to say these guys are very patient and quick to analyze and send you maps back quickly. My car runs great without any issues. I couldn’t have asked for a better e tuning process.

Hats off to Stephen Clark!! I recently had a tune done by him at iAtuning and what can I say; car drives fantastic, his knowledge and professionalism is extraordinary. He gave me solid advice on some parts, walked me through the whole tuning process, and helped me troubleshoot some issues. My 2002 wrx never drove better and the extra power is always a plus!! I highly recommend his services to anyone looking for a quality e-tune.

Wanted to post a quick thanks to Stephen at iaTUNING, got an etune from him on my 04 wagon and the results were great! Quick to return emails and answer questions. Knowledgeable guy as well! If you’re thinking of getting an etune you won’t be disappointed the results are great!

Default iaTuning E-Tune review

I normally don't do many online reviews but I have to give credit where credit is due. First I'll start with how prompt and timely Stephen was from beginning to end on the whole e tune process. After sending him vehicle specs and a list of what was done to the car he had an initial base map ready to go within one to two businesses days and that stayed consistent through out the whole tuning process. We ran into some problems during the tune (boost leak and cylinder misfires) but Stephen's ability to look at data logs and pinpoint the issue right away made me feel that my Subie was in good hands. Stephen was able to guide me in the right direction to get the problems resolved and continue perfecting the tune. I will say I am 100% satisfied with the final Tune the subie rides and drives great and the extra power feels amazing. The service provided and was worth every cent. I will be using aiTuning for future tunes as the subie gets more upgrades. So big thanks again to Stephen Clark at aiTuning for the excellent customer service you have a customer for life.

Smile Stephen is awesome!

I’m 100% satisfied with my e-tune with Stephen, I always do dyno tunes and never tried a e-tune, he make the whole process way easier than expected. The tune itself pulls hard on my car, even at 65k miles in my 16WRX, It wake up the hidden power of it. Got idle issues since EGR delete mess with the fuel system and Stephen quickly solve it without hesitation. The tune was meticulously reviewed by him and correction were timely done. Thanks Stephen Clark I will recommend you to my fellow Subaru friends and will consider my next tune with you soon.

I'm still undergoing my tune with Stephen at IAtuning, he was initially extremely fast and professional.
Recently though, I haven't heard from him in 6 days, makes me hope he's okay. Obviously, I'm anxious to have my tune finished.

Default Great tuner

Stephens a great tuner, I'd love to be able to work with him in person and get a dyno tune if I ever could. It took him 3 days worth of logging and I got my tune, and it was a quick and easy process with very detailed on what you need to do to acquire the logs.

Needless to say, I'm way more than satisfied and I am loving my tune, wayyyy better than cobbs ots stage 1 map. I'll be getting it retuned soon when I get my parts in.

Bought my car pre-modded with some MAPerf parts...was unsure of tune status so bought the MAPerf OTS map...got under the car to swap out the horrible straight pipes with an Invidia Q300 catback and realized I had a Perrin header as well.

Figured it was in my best interest to get an e-tune for scheduling concerns due to being a dual working spouse household with kids.

Found iAtuning through reviews on this site and decided to go for it.

Stephen was very responsive with MAP turnaround time and suggestions, very professional to work with and sends detailed instructions on do's/don'ts and which parameters to log in his first email.

The car runs great and I can tell there is more power everywhere when compared to the other company's OTS map.

Will definitely be coming back when I add on some more upgrades.
