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.

i like it.

Reviewed By Jeff H (INDIANAPOLIS, IN) Reviewed for a 2009 Pontiac G8 —1/10/2013 10:35 AM

This was my first tuner that i have bought. the ease of install is great. if you use the little pamflit that comes with it you will be up and running in less than 5 min. before you start messing with all the nice features this has i recommend that you read the manual. i have noticed a killer throttle response and my shift points make more since. haven't noticed that much of a MPG increase yet but with any upgrades your foot seams to be heavier on the long pedal to test what you have.
