That only took about ...what 2 months......slackers

boost controller?...yeah ok then i ask when do u plan an engine rebuild?get engine management not some boost controller...and if you just want some more boost and not alot just get a ECU reflash program
Nice STi btw!
do they blow up easy or what? -
2.75 i think.

The problem w/ the WRX (and I assume STi as well) is that the factory ECU always tries to get it to wrong at stock performance, no more and no less. Sometimes it will cut/add fuel, others it will advance/retard timing. BY FAR the best thing you can do to squeeze more power out of a Subie is with an ECU reflash or Piggy-back/stand-alone ECU. ECUtec is probably the most popular reflash, TurboXS UTEC is probably the most popular Piggy-back and Elementtuning IMHO has the best overall package (I THINK its a piggy-back as well, but it may be stand alone).

doesnt he already have 3'' exhaust? i spose a downpipe would atleast be logicalSTI comes with factory a downpipe....1 3/4" i think
-
I'd hope the stock downpipe is bigger than 1 3/4" on the STi, I believe the stock WRX one is 2"+ (I'd go measure but I'm lazy). What I think they meant was a cat-less downpipe around 3 to 3 1/2". Actually, every turbo car comes w/ a downpipe, otherwise the exhaust would just exit directly from the turbo.....
-
i dont think they would put anything bigger than 2inch on a stock wrx or STI

I have had a boost controller on my STI since I basically got the car and have have absolutely no problems, although you do not want to go over 16 psi otherwise you will just detonate and the ECU will pull timing anyways.
The DP on the STI is the same DP on the WRX. STI does have larger stock exhaust on it and the other major difference in exhaust is the STI uppipe is catless. If you want to do a turboback on the STI you WILL NEED to port the wastegate otherwise you will get boost creep.
Element tuning ECU is a full standalone along with the capability of removing the MAF and going to speed density. SWEET!

Mine was 2.25" stock

Im not saying your going to blow your engine...its just most ppl wanna turn up the boost and they think hey i'll just spend 200bucks on a boost controller to crank up the performance instead of $500-1200 for an ECU program or Piggyback system.
They are safe if you arent an idiot ricer about it but for the most part i'd spend the $ on an ECU program or some engine management that changes all of the perimmiters and not just boost.Almost everymod will have an effect on what your ECU is doing...most intakes lean out your mixture and most ppl wouldnt do anything about it even if they already have a car that runs lean. I just think cheap mods like boost controllers and Super AFC's are junk and are a cop out to "real tuning" Just my $.02

I'm confused? First it sounds like the STi will blow up with a boost controller, but next, it wont blow up if you aren't stupid about it. I guess what I mean is, Kirk wouldn't go fiddling around with his boost controller, cranking it up to 30psi... And he has the people to help him not run lean / blow things up. Honestly though, $200 for a boost controller?
Also, I dont really understand why S-AFC's are junk... care to elaborate? I guess all of us with just boost controllers and afc's don't really "tune" our cars? Hmm... I guess we should just ignore Nick's conservative "piggy back" afc tune for 530whp...
