Maybe its the dbw on my truck. It seems like the idle is set a too high and theres is a delay when letting off the gas. When its cold it sometimes idles to 20-30mph without any foot on the gas. Its annoying.

I did the headers, exhaust, CAI and tune with little to no change. I did the drop, gears and UDP and only tuned the speedo calibration later.
