Big difference in power. I get 3 to 4 mpg more when using performance level.

Oh my gosh. This thing is bad ass! Made my truck a lot quicker right after I put it in. I'm getting 16+ MPG with 35s and made it start spinning when I punched it at 45! What are you waiting for? Buy this tuner!!! You will not be disappointed! Also, always pleased with AutoAnything!

I used the premium fuel setting, 100% shift firmness, recalibrated my Speedo, up'ed the rev limiter and shift points and the speed limiter and it only took five 5mins and I can definitely feel the difference. IT was as big of a difference as my cold air intake worth It! I can also feel more power even when it's not wide open!
