Thanks for the info Corey. I think my tire size hurts the performance.
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.
With my CAI and the canned tow tune it seems to drone alot (sounds like a vibration in the CAI) will the custom tunes help with that. I didn't notice it as much in the canned 91 tune. Sorry for so many questions this is all new to me.
