I was wondering if STi need some sort of an engine management to tune the car? Or it's like evos, which you can just do a reflash on the stock ECU?
What's a rough estimate for a STi to get on a dyno with downpipe, catback, intake, bov?
One of my friend got a STi recently and put on all those mods that I have listed above. He's one cocky kid and thinks that his car can whipe my evo anyday after he gets a tune. Thanks

 

Go do a search on NASIOC.com for BPU dyno numbers

Also what MODs do you have.......

and to help you out just this one time, yes you can flash tune a WRX/STi

 

about 300whp with a tune for the STi. they can get reflashes, like us. pls list your mods. thnx

 

i got 302 with just a exhaust and intake on my 05 sti. i am currently sitting at 463 on 93 and meth and 504 on c16 and meth. running the perrin gt30r kit with some other stuff. its all in the tuner. i go the TOPSPEED for all my tunning needs.

 

nice #s kimma, im looking to get my 50 trim kit put in and tuned by turbotrix, hopefully with alky ill be at or near those #s.
