Wow, the stock tune on these things is super conservative. The 1st gear WOT shift is 5725 rpm, 2nd and 3rd gears are both 5425. Is there any reason I can't go 5900 for all 3 gears? Stock engine extreme cutoff is set to 6100 rpm, overspeed lamp comes on at 6000.
Anyone have experience tuning GM 6.2L trucks? I'm open to suggestions. This Yukon is a Denali with an LS3 throttle body and bigass airaid dry cone intake, which is why I want to rev it out to 5900 rpm.
I've already reduced the torque management and smoothed out the shift pattern to something more responsive. Stock tune attached.
