"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." —Jeff H from Indianapolis, IN bought a DiabloSport Trinity T-1000 Programmer for a 2009 Pontiac G8.
