How do you improve part throttle response? Ever since my stage 2 heads and ls6 intake install, my low rpm and part throttle response has suffered. Car feels weak down low at part throttle or WOT, it builds power after 4000 rpm. It is suprising since i have only a 224/224 114LSA cam, not a wild top-end cam at all. What can I do in LS1 Edit to improve this? Thanks
Re: How do you improve part throttle response? Have you tuned your fuel & timing after cam install.with a cam your car will feel weak intill you start tuning the timing.

What is your full list of performance mods? Has your PCM been modified in any way? Do you have access to Autotap? Have you done any log runs in Atap? If so, what did the parameters read after the worksheet was finished?
You need a tune in that beast

Re: How do you improve part throttle response? If the port volumes are considerably larger than stock low rpm becomes sluggish. Dunno if you can do anything for closed loop part throttle other than playing around with timing and verifying everything is OK in the logs.
