I just got my tuner today and started off with a tune off of the repository, 1,2 shift is too hard and would like to know the proper way to smooth it via tuner.
also im not 100% sure but it seems as if it is running way to lean with this tune, any help would be appreciated, I understand some things involved but im a diesel mechanic for international and we work with completely different machines lol.slight mods.hpt
slight mods include k&n filter, no cats, flowmaster 40 single in dual out, and 34" tires. I want to get the most out of my truck as it is until I delete the dod and install my ls9 cam.
