I have a 2016 l86/8l90 combo swapped in my 48 Chevy pickup. I have doing a little tuning with the MAF and VVE tables. I have also disabled DOD, DFCO, and Catylst. I have a CAI and a a free flowing exhaust. The main thing that is annoying me on this swap is the crackling with the free exhaust that it makes after revving it and letting off in neutral and park. It also does that annoying sound on shifts as well.
When I datalog it, from my amateur tuning knowledge. The computer seems to be pulling/adding a decent about of timing during these events under the Torque Management Advance. This seems to be retarding timing rather than adding.
Would this rapid change be what's causing the crackling/popping through the exhaust?
If so what would be the tables that could help this.
Thanks
