is there anyway to have multiple tunes programmed for the car and flipping through them?

 

only way to have a tune on and off is through trifecta and that is occupied with the cruise control button. trust me you dont want a trifecta tune either, mise well get a nice reliable tune from a reputable tune via hp tuners.

 

Do we know why nobody can figure out/HPtuners can't have the same on/off feature?

I thought I saw something about BYT altering trifecta files and they were able to achieve something similar

 

The nGauge currently supports Fords, while the datalogging may work with other GM vehicles and some of the PIDs, it is not officially supported yet. Once it is though you should be able to store quite a few tunes on it and swap between them just as fast as you would using HPT

 

well as soon as u can do that, I'm getting it
