^I can say the same about turboing a p5 especially without internal work. But that mp3 ecu its all the n/a guys really got. Header, intake, exhaust, etc still wont make that bang for buck hp.
Personally, my car runs like crap on 87oct but I also dont have a clue what the previous owner did to the car. But Ive had this car for 3 years and havent touched it just because it lacks any sort of power. Spectra5's with just exhaust make more power to the wheels then we do. Its a shame really
