Okay, after trying out the MPG Booster tune for a week and 2 tanks of gas I have decided to go back to the 93 oct tune! First of all my MPG dropped by 1-2MPG rather than increased. Secondly, and the only way I can describe this, the truck just felt like it was dragging something, like it was being held back. The tune wasn't bad but it just wasn't good like the 93 tune was when I installed it and since I wasn't getting any MPG boost I figured why keep it in there.
After putting the 93 tune back in and turning off MDS and setting my tire size again I simply drove it around the block and could immediately tell the difference and felt like the ZAZZ was back!
Also, I just paid $4.09 for Super 93 octane and that's the cheapest I've paid for gas since I bought the truck in February! Yay!
