We'd need a bit more information. To my knowledge an L67 didn't come in a trofeo. We'll need to know the year and rest of your mods besides the ones in your siggy.

Ok..we are getting closer. You are running the OBD1.5 engine on the Trofeo'* ecu. See..the sc you have has coating on the rotors and creates more boost. By running a 2.0, thats a drastic size.

I think you'd need to crack the ecu programming to tune much.

yes it is the 225 hp motor
and i did rebuilt the charger and pandp the intake
this summer i plan on running the 2.0 a LQ4 maf and a ported throttle body
i also ordered the mini afc 2.2 because it leans out on top alittle and then i has some knock.
i spray some water/meth to the tune of 50/50 and that cools it down but i want to be able to only spray when i want more power not all the time im in boost.

have you dealt with mini afcs b4 or not??
my block learn mean (LTFT) is at 110 128 =14.7to1 air fuel
so the computer is seeing rich and commading lean which is bad
i want it to see lean and command rich right??
i havent had to do much tuning other than physical replacement of parts the computer in those cars can handle a large amount of mods but i have reached the end of its limits im afraid.
