I have here a 70's Silverado with 2003 5.3 stock engine. I notice it has LS2-type intake and headers. The T/B is 3-bolt model and the intake is 4-bolt and it has adapter in between.
The problem is that the throttle response is very agressive. It's hard to drive moderately on slow speeds.
I was thinking of changing "desired throttle area" but there is that notice that tampering with these values may brick the pcm. Should I worry about this?
Tune and log attached.
