I have read through the Whipple and MPT tune threads and still can’t make up my mind. I’m looking for better shifting, smarter gear choices, better throttle response plus more low and midrange power for hills. My biggest issue is maintaining a steady speed on a grade. It seems like it bogs so I throttle up and it shifts then throttle up more it shifts again spreeds up and I’m back off the throttle and back at the throttle all over again. I traded a 5.7 tundra with a 6 speed and it felt much more intelligent as far as the transmission goes, plus more responsive to throttle input. I also own a ZL1 Camaro and an Escalade with the 10 speed auto and they perform perfectly. This truck feels awesome when you wack it and let it pull but very lazy under normal driving situations. Open to any input. Thank you.
