Which other tunes did you try? Also, are you filling up with 91 each time now?

 

I did the mileage xs first and I noticed a difference but the mileage was not that much better. I tried the 87 tune after that and it was worse than the stock settings! The performance 91 has suited it best. Yes I have to use that octane level but there is a gas station here that does the price of mid for regular on Sunday's and Monday's so I'm not really hurtin there.

 

Correction. It does the price of regular for mid. I'm sure you understood it, but I didn't word it right.

 

I had put the towing tune on recently for a 200 mile trip through the mountains. I must say that it seemed worse than the 87 had been handling things. I will try the 91 next time I need to fill up to see if that seems decent.

 

Yea check it out. Just like what the other guy said on this thread, "nothing with the superchip has that WOW factor." but this tune has shown the most difference by far. Hope it works out for ya!
