New heads installed and now the car bucks under light loads under 1700 rpm? First off my car is a 02 Z06 with all the boltons( cold air, 30's headers etc) and a 228/230 .571/.573 112 cam. I've had this setup for sometime now have it tuned perfectly via edit. Just recently I installed a set of AS 5.3 stage 2.5 heads. The car runs fine and has made some awesome prelimainary 3's on the dyno. However I'm **** when it comes to driveability. Recently i noticed that if u let the revs drop below 1700 and slower and try to cruise or carry on the car starts to buck. What should I be looking into in edit to change-could it be something with my IFR? I had it set at 105( with the 30's)before the heads and left at 105 after the heads. At wot the LTFT go to 0 so i just lef it alone-should i be looking at finding out my average LTfTm's again? There used to be an excel spread on finding the average-does anybody have it or should i be looking at something else? Thanks.
