Got an 01 Yukon with an 8.1 in it. Going in and tweaking the tune to my liking. I read that the electronic throttle is real lazy in them from the factory and would like to make it act more like a cable throttle.
I can't find any solid info on which tables to adjust though. I think I see where but also see the warning about killing my ecu so I don't want to go blindly messing with stuff. Any insight? Thanks in advance for any help
