Hello guys i tuned a 05 lly with a 50 hp tow tune all runs great but i have a turbo bark threw the air filter at 2200 to 2400 rpm seems to happen under a load at 3-4 shifts with about 50 percent throttle possibly because of the defuel during shifts. i have reviewed on the forum some and it seems shutting off the egr is first to fix the problem but im not a fan of shutting off egr in a smog
