I'm tuning my tahoe right now and trying to get some odd ball idle issues fixed. I did the raf log but I'm wondering if it's too high. I don't have a bad cryise control but I do have bucking with Tcc locked at 35mph and just bearly applying throttle. My raf log told me 16.xx in the operating temp zones and that gives me 15% throttle at idle. This seems high to me. It's a cammed L92 with the stock truck Intake and turbo charged. I'll post some logs and tune in a few, I'm in my phone right now. Cam is a 227/235 on a 111lsa.
