I stick mine in tow haul mode, it seems to hang on to all the gears a little longer Perry.

Thanks. I do too when I remember to, and it does indeed improve some.

Thanks. I'm still kicking it around.

i went with 5 star. Got like 8 tunes. Love it. It holds gears just right now. Doesn't hang too long though. I run 91 performance street or something like that. I get 13-16 in town and 16-19 highway. I have 3.73's. Max tow package. Typically 18 highway and 14.5 in town. I also have 1.5 inch lift with bilstein 5100. Stock tires tow mirrors. Rear sway. Bar. Truck handles like a dream now after the rear sway and that 5100's. Those are must haves

Thanks for the feedback. It looks like the performance tune/91 oct. is about a wash for stock/87 oct. when it comes to $$ per mile, but you get a performance boost. Does that sound quasi-accurate?
