i have been using my supra(87 turbo) as my DD since august and at first it felt pretty fast because the car has downpipe 3" exhuast lower hardpipes and an intake. She was pushing about 10psi and everything was good until the car just started feeling slow one day.So i checked for codes did a tune up (still felt slow) then turned up the boost to 14psi and what do you know it felt fast again. So its been fine since then but now the car is starting to feel slow againg lol and i can't afford a bigger turbo yet:cry:. Its kinda of scary how addictive boost is lol it seems like every day i think about how i can get my fix lol is it me or is it somthing everybody goes threw:1zhelp: ?lol
