I'll be using my L86/8l90 for commercial use. Is asking my tuner for a loaded/unladen tune a silly question?
The idea is I turn my phone into a Hotspot to communicate with HPtuners and switch to a more mpg friendly tune program on my laptop. One tuner said that I would basicly have to retune every time.
I know gas engines aren't as flexible as diesel on fuel maps, but there has to be some variables right?
