I really don't know much about tuning especially not gassers.. but I did a little on the transmission so I already have the VIN licensed for my dad's Yukon so I thought I might as well try to fix another complaint my mom has about it. The really touchy throttle. I know on the diesels you can easily modify that with the fuel limits per throttle percent. Can I modify the Throttle Open Rate Limits to do the same thing or should I not mess with the table? What are the limits if I do mess with it?
