I have an LT1 motor controlled by 411 PCM. When I blip the throttle there is almost nothing there(RPMs go down) which makes for tough time driving a stick car. On the other end of the spectrum, when I get into the throttle fairly hard and let out the RPMs hang up BAADDD....motor will literally stay revved at 4500RPM or 5k until I shift and get it into the next gear. I have had to shut the car down with it hanging at 6k RPMs before when getting into it hard and then throwing the car in neutral.
I believe it is throttle cracker and follower I need to mess with, but It appears as they are already maxed out in the software? Should I go back the other way? I haven't really messed with it and don't have a full understanding of how it works. current_01.ctz
I attached my tune file. Also, the car is Procharged 396ci, monoblade throttle body, Manual Trans
