cammed ls2
awd 4l80e with 4l60e tune and conversion harness
3200 stall
Truck was 80e swapped for about a year before the cam swap. never had any issues that I noticed, but maybe I didn't make enough power to notice it.
On a WOT launch from a dead stop about 4500 rpm in 1st gear ONLY I get a LOT of torque management pulling timing and closing the throttle. 2nd and 3rd gear are fine, no issues I can see. you can see it in the log and feel it in the truck, power is way down at the top of 1st then on the 1-2 shift the truck feels like it picks up 100HP due to all the timing coming back and throttle opening back up.
anyone have any insight on what I may be missing with the tune?
