Since the tuner and delete, Its like a new truck. No Xtra oil in the crankcase. My question is, do i have to leave the tuner connected or can I unplug it and keep it in the glove box? Im running it with no additional power so there shouldnt be anything to monitor. Has anyone done the trans program, Is it worth the $300?

 

What tuner are you using?

 

I'd bet H&S XRT Pro way he's talking. if so just upload and put in glove box. Smarty is same way except I don't think it has transmission tuning.

 

Its an H&S, with out pyrometer.

 

Hes talking about the black maxx or Mini Maxx. Yes it has to stay connected. I
