Default TDC or PDX E-tune?

Im looking for opinions on the PDX e-tune and the TDC e-tune for my wrx w/cobb stage 2.5. Is there a better one of the two? Does TDC give you the same number of real time maps to go with the base map as PDX does? How close will the power numbers be in relation to taking the having it road/dyno tuned? Will one tuner crank out more power? Let me know because I am going to do one of the two within the next two weeks.

I just ordered my PDX e-tune, hopefully I will get it tomorrow. I think they both do pretty much the same thing, I am not familiar with TDC but I hear good things about both. You can send your datalogs to them and they can refine the maps as needed.

If you can afford it, get dyno tuned with a live tuner and a wideband.

I just received maps from PDX. I'm running a 34 with all supporting mods. Having spoken with Jarred for a lengthy time I am very confident. I intend to data log and will post the results and my impression in the near future.

PDX will include the Data Log sight in the E-Mail containing the Maps. They encourage data logging and upon reviewing the results will tweak your map as necessary. I am very impressed with these folks and believe that they are sincere and honest. Boy, what a concept!

Sounds like a plan, I trust that PDX will make it right the first time but just for piece of mind, I'll probably send them the logs to ensure everything is kosher.
Thanks for the info.

I used Jon @ TDC for an in person tune, but I don't see any problem with his eTune service - should get similar results.

What items should I log to send to PDX? I just got their maps (which I am loving over the Cobb stuff), and want to send them a datalog.

I'm interested to see how yours work out. =)

sounds like pdx is the way to go. I live in seattle so it wouldnt be that bad a drive. How much more power am i looking at from e-tune to protune. Would it be worth the extra money to drive down there?

I would think there may be like a 10hp peak difference. You may see more power increases in other parts of the RPM range with a protune though. You can be sure your AFRs are where you want them also. I would think a live tune can be more aggressive and safer than a e-tune usually. But for many people the cost of a live tune and dyno time is just not worth it to them.

One thing PDX does not do very well is fully market the product that they are selling. I think this is a major marketing deficiency for them because they would sell a hell of a lot of maps if people knew more about this program. When you call them and ask for a PDX map they actually send you a number of maps. I got the stage 2 maps for a USDM STI and they included:

The base map - Conservative base map not necessarily meant to be run alone but its possible if you really wanted to.

Main realtime map - Relatively aggressive in timing and boost. This map is huge on performance with boost targets around 19psi but it may be a little over the top for some peoples safety concerns. PDX insists that the map is safe for every day use though.

low realtime map - A conservative map built for safety with boost targets of around 14psi. Don't be fooled, this map is very fast and the engine runs very very smooth. I have settled on this as my every day map reserving the main map for higher performance applications.

aggressive realtime map - This is not for the faint of heart! I have not and do not intend to run this map but its got to have amazing performance. I would not even attempt to run this on anything less than Sunoco Ultra 94. PDX very clearly told me that if I do intend to run this map on occasion I could carefully monitor the car. It may be a good map for street mod Auto-x but I would never run it on the track or on the street for long periods of time.

Race fuel realtime map - Yes thats correct a 100oct race fuel map! This map is a lot like the aggressive map only its meant to be even more aggressive. If your looking for a great way to blow up your motor then run this map on pump fuel...

Stage 3 map - This is basically the main stage 2 map with the addition of injector scaling for the perrin 816cc modified injectors accompanied by a Walbro 255lph fuel pump. I assume that this map will net over 300whp which I plan to verify on April 2nd when I get my car dynoed.

By the way, I decided to get a wideband o2 sensor yesterday to check out my AFRs. I will report my findings in a few weeks once I have everything up and running.

It's worth the drive to see and hear your car on the dyno and watch these guys work. I'm a total jerk and haven't give them any money but they still let me watch dyno days.

PS - I think PDX does a relatively poor marketing job because they have more work than they can handle right now...
