I have been to a few different websites and see a typical dyno test of a celica gt at about 122 horsepower at the wheels. On my 2000 celica gt 5sp I have the following mods. AEM CAI
, Borla exhaust, Hotshot racing header, Jet performance chip. I should have a conservative horsepower gain of about 25. However I have had mine dyno'd recently and It came up with 128.9 at the wheels (in fourt gear) and 112 for torque. What gives, do celicas not respond to mods very well? Every mod says it would give me from 8-12 horsepower at the wheels. Is this not correct? Also my car has about 50k on it and has not been ran hard.
