Looking for some input/advice,
I recently changed the cam, exhaust, pulley etc. on my 2012 ZL1 and after some tuning by a local "professional" it seems to run and idle faily decent. I havent run it much yet, just took it out and logged some part throttle data. Issue is the throttle seems "lazy" on the bottom end and at take off. I myself made some changes and its better, and possibly the best it will get with the engine mods.
Wondering if someone has run into this before or could look at the tune, and log to see if there are any other changes that could or should be changed.
BTR Stage 4, 235/252, .628/.600
2.5 Pulley with mild porting on the snout
1 7/8 long tubes, high flow cats with 3" and no mufflers (currently)
