Best deal I could find for this product. Product performs great and I couldn't love it any more.

The down and dirty: Yep, got a nice 93 octane tune. The iPhone interface to do this is slick and I would not say slow But: After a few days the module you get that plugs into the OBD II data prt died. It flickers as if it will startup, then dies So: I am very pleased with the tune. The power increase is noticeable and the shift points aren't ramped up to obnoxious levels. i have not given cust supporter a chance to rectify.

Amazing! Installs easily, and great options. Screen is a little touchy, but you can get around that. On 87 Economy, my gas mileage went up 4 mpg. Ive been running it on 91 Performance the past week...wow! I have 35X12.5X20 and she smoke the tires. Shifting is smoother and when you need to pass...she'll pretty much get up and take off. In 91 Performance, i am still at about 1.5 -1.7 mpg better than at stock. Well worth the purchase.
