I have a 2002 Duramax with Cold air, re-built Allison/Suncoast trans, and a 6 stage Edge chip w/hot code. I can get it to smoke for a couple seconds but I was wondering if anyone had advise on an easy way to get it to roll it thicker and blacker for a longer time? Also any tips on a way to increase the turbo whistle would be awesome.
