Ok, going from my '99 Silverado to '04 Avalanche, I noticed one major thing. The throttle response on this thing sucks! I know that it is a bit heavier than my Z71, but the response just isnt there. It seems like when I jab the throttle, it takes about a full second or so to start responding. I have removed all TM except the injector disable when traction control kicks in. The ETC max throttle percentage table is maxed out, so I know that is not limiting it. Does anyone know of anything i can change in the tune to work this out? My part throttle timing I know for a fact is maxed out, and the AFR is perfect. Anyone!?
