Great Product!

Reviewed By William P (WICHITA, KS) Reviewed for a 2009 Pontiac G8 —7/11/2017 5:01 PM

This product was exactly what I was looking for. I have a 2009 G8 GT and I wanted to rid the 4 cylinder mode and that's what it did. I plugged it right in and have been in 8 cylinder mode for about 3 weeks now. Throttle response has improved at all speeds. The only thing I worry about is the battery draw which I should not have a problem with since it is driven daily. Great product but a little pricey.

Easy to use

Reviewed By Grant C (HARLAN, IN) Reviewed for a 2018 Chevy Silverado —6/15/2018 8:30 PM

After a quick update and vin unlock the tuner was easy to use. It would be nice if it included more detailed instructions about adjusting the shift points. I bought it to be able to adjust for tire size and gear ratio. It does both plus includes canned tunes for less than the price of other products that simply correct for tire size.

Fantastic but overkill

Reviewed By Scott J (Manorville, NY) Reviewed for a 2018 Chevy Silverado —5/29/2018 8:10 PM

Great tuner. Love the screen, and the fact it's touch. Diablo still working on tweaks for my 2018 Silverado 5.3 but satisfied with the tune loaded.
