I can't find this information anywhere.
My 2013 Impala with LFX V6 will not open the throttle blade to 100% until about 4300 RPM. It is bone stock mechanically. How do I remedy this in the tune? Do I have to modify virtual torque tables? I believe the engine torque is being limited by a table I don't have access to. It bogs really bad on launch until I hit right around that 4000 RPM mark.
