installed gryphon

[robandkat]

I just received my gryphon, and installed it. It did not make a huge differance in the tow mode. I played with the performance 91 tune and it was better, but I thought it would make more of a differance(I was running 91 gas). I ordered an 87 custom tow tune and an 87 custom performance tune. Are these tunes going to wake the truck wake up alot more than the canned tunes? Also, should I order a custom 91 tune, would it be that much different than an 87 custom tune?

I also used 2689mm for 305/65/18 bfg at/ko tires that are 33.7 inches. This should correct the speedometer right?

After I get the custom tunes, if I change tires sizes, can I just change it in the tuner or do I have to get my tunes redone for the new tire size?

Sorry for all the questions. Any other suggestions would be greatly appreciated. I did not mess around with any other custom features because I am not sure how they would affect the truck.

Thanks for your help and suggestions!!
