my car seems to pull better at half throttle than full what does that mean need better ecu?? timing?? air??? fuel? ne help is a 11.5 to 1 ls vtec with stock p 28 ecu? ne help would be great.. NA IS BEST ffi (fu*k forced induction) lol j/k boost is fun!2

 

help whit this? ne one?

 

try chipping the p28 so its a DOHC ecu. that might help some.. i think the fuel and ignition curve is different than the stock p28.

 

you know what i swear to god that my car does the same thing sometimes... its a b20z with bolt ons
