Not a must but you won't gain much power wise without one.

The wives tails is no you don't need a retune, however the truth is, if there is a difference in pressure drop between the original and replacement, you will need a retune. I had a 3+ psi overboost when i swapped out my STI TMIC to Spearco. I was hitting near 25psi, which is well beyond what it was tuned for with the STI TMIC.

this brings up a whole other can of worms, maybe I should get the Turboxs TMIC in lieu of the STi TMIC, mainly for the lack of pressure drop, meaning I can either a.) run less boost but get the same results, and put less stress on my turbo OR run more boost, get more power, and put the same stress I would have on my turbo with the STi intercooler.

STi intercooler can be had for 300-350 with splitter, OR I can get the TXS for about 600-650. Damn you internets, stop giving me choices!!!!

One of the best if not the best TMIC is the Spearco...

Spearco is overkill. For 300ish AWHP just get a STI TMIC.

I have an 07 wrx sedan 91K miles and currently it has TBE and intake with a dyno tune


honestly, Im doing the SAME upgrade and from what multiple tuners and posters have told me for 300+WHP and wtq this is all youll need on top of what I already have:
STi TMIC
VFXX turbo
fuel pump just as precautionary- Its only 60-70 bucks anyways
tune- road, pro, cobb or dyno

other accessories to help gain that extra HP: Intake, uppipe

If you get the parts locally youll save a lot of money as well just my .02

Dont need to upgrade the trans, motor, injectors or any of that, the 06 wrx has 2.5L just like the 07 sti unlike the 02-04 wrxs which you need to upgrade the injectors and other stuff

regarding clutch, I have the stock one but if you dont launch it you should be good for a while, but Ive been told eventually Ill need to replace it probably to a stage 2 clutch or something like that
I DD my car as well probably 17-20K miles a year, I know exactly what youre saying, just dont launch or beat the piss out of it every time you drive and you should be safe

honestly I saved 300-500 not having to pay for having everything shipped which basically gives you a free tune in essence!

VF39 turbo was $150(long story short,..guy had NO idea what it was worth)
sti tmic $200
fuel pump $60
splitter $70
uppipe $80
and the TBE and intake came with car when I bought it so $560 I upgraded from my wrx turbo setup to an sti and net about 80whp and 50wtq from it

If you plan to never make more than around 300whp, then yes it's overkill, but if you plan to make more then that in the future, then no.

Anyone think I should be hitting higher than 281
It's how your car is tuned! I'm using an Access Port which allows me to try different tuners via email and Datalogs. Your inter cooler isn't holding you back at this point, unless your living somewhere hot. I'd find a better tuner and then decide what parts you really need. My 2011 STI 306hp 344tq I have a turbo back, CAI, Cobb 3 port and AP I got it tuned from one tuner via Internet and then Dyno'd from another tuner just to see if I was getting ripped off. So find a better tuner and then buy parts then tune again..

I am going to get a retune in mid feb any places to recommend I know Cobb does a good job or any other parts I should look into that helps out just a little more to free some power and allow the current mods that I do have to increase a little more production in power

This is the only reason I'd consider a Spearco or TXS - If I get hungry for more later I'll have to buy a better TMIC (I want to stay TMIC). Although honestly, I could probably turn around and sell the STi intercooler for roughly what I paid for it, so it may be a moot point. Also at that point I'll be throwing gobbs of cash at the driveline anyways....

I'm still wandering why people with a cai and exhaust and a tune are hitting 330 whp and when I we to Cobb with the mods I have on my car they said 281 whp looks good it doesn't add up.

Number are numbers. Dynos read differently. 280 on that dyno can be 330 on another

Default wheel hp

The readings depend on the brand of dyno, temp, aggresiveness of tune. My expexperience on a dyno jet is that a stage ii + set up and tune runs btwn 280
- 300whp with 19 psi boost 93 octane. If someone runs e85 or a more radical tune 330 is possible. My suggestion is not worry about "bench racing" dyno numbers are best used to measure base line and changes on a car not who's is bigger than there's.

There are two things that will get you 300+ WHP on a vf turbo:
- a high reading dyno
- E85

Everything else is fluff. The difference between an STI intercooler and a Spearco is pretty small on that turbo. Where the intercooler helps most (high RPM) you've already hit your power peak (VF turbo on 2.5L hits peak power around 5500)

It's not worth it to chase a number with a vf turbo. The difference between a header + TMIC + TGV deletes, etc... vs a basic turboback + tune is not much. If you need to feel like you have 300 WHP, find a place with a nice high reading dyno and take your setup there so you get your 300+WHP chart. If you want a great driving setup for little money, then get a turboback, a fuel pump for a little safety and a tune and you're 95% of the way to where an additional $1500-2000 will buy you on the stock turbo.

The reality is that there are dynos out there where no pump gas vf turbo setup in the world will crack 300 WHP, and there are other dynos out there where a downpipe plus a tune will break 300 with ease. The sooner you realize that the dyno is the biggest factor in the numbers between pump gas vf setups, the happier you'll be. Chasing numbers is for people who want to feel fast. Chasing times at the track is a different story.

Funny, trap speeds say 300+ is quite accurate.

Also funny that chasing numbers on a track is magically better than chasing numbers on a dyno. Your clearly biased opinion could be better illustrated to not be so hypocritical.

Track numbers are proof of a fast car not dyno charts. I agree with him on a lot of what he said. Not all but a lot

They prove accuracy of dyno numbers. There are far too many 110+ trapping stock weight vf cars for his comment to be anything but anti dyno propaganda, its obvious based off his comment that that's his agenda.

I agree that dyno numbers are stupid if not used in comparison and tuning. But to act like its any different to chase an ET or trap speed is asinine.

"My goal of 12s is better than your goal of 300whp." Might as well make it a dick measuring contest if you see it any different.

I'm just saying as far as an accurate measurement of power it is going to be at the track or you need to have your car dynod stock so you have a baseline hp measurement. 2 routes you can go. But for someone to compare their car to another car on a different dyno and day is not going to say who has more power. We can talk about this all day but track numbers are "usually" the best way to compare car against car. Obviously elevation and temp play a huge role in dyno or track but numbers are numbers on a dyno

I know what you're trying to say.

But what you're not taking into account is track timing differences as well. There are too many non Nhra sanctioned tracks too. I've run my same car in identical conditions at two different tracks and the differences were enough to dissuade me from thinking anything concrete about different track comparisons.

Somebody running in -2500' DA at ATCO vs somebody running 8000' DA Firebird raceway will give you some pretty wild differences that no conversion can make accurate.

I'm not worried about the numbers in a sense I just think that the car can have more power with what it has on it so even if the dyno at the Cobb has a certain number that it gives me I believe I can get more out of the car so I want to get another tune and see where the numbers are at then And I believe I can hit higher numbers than before

Cobbs dyno reads high. Also why post here? He is asking for a platform that is extremely different from yours

I'm just asking here because its in the 300+ section which I believe my car should be hitting with numbers and is hitting on the streets was just asking a question I didn't need trolls about it. So is there another place in Dallas that does better tuning than Cobb

Not trolling just providing information squid....No Cobb in my opinion and the opinion of many others is the best they are a great shop and Calvin does an excellent job.
