"I was most impressed by how fast it tunes your vehicle and goes back to stock in a matter of 4 minutes I mainly purchased it to eliminate my DOD it works I used the 91 octane tune and removed my speed limiter I tried both firm and hard shift mode which makes a big difference but I use normal shift because there are stories about my transmissions reliability my gas mileage is crappy with or without DOD it always says avg milage is 18.9" —Kenneth C from East Boston, MA bought a DiabloSport inTune I-1000 Tuner for a 2009 Chevy Impala, SS, 5.3L V8 LS4.

Jet Performance V-Force Plus Power Control Module


Overall was a good buy. I didnt know that the tuning was pre programmed until I got it installed, which took forever because the manufacture directions were wrong. I have noticed an increase in power and proformance, and I have notice my gas tank last about 3 days longer. Im dont think its the chip doing it though. The display shows me how much gas percentage wise Im using, so its making me drive smarter. View more reviews...

Range Start Stop Disable Solution

Range Start Stop Disable for Chevrolet

The performance of the Range Start Stop Disable for my 2015 Impala has been excellent. It works flawlessly and you will never even know that you had the start stop feature. The other side benefit for owners with this type of technology is that your equipment such as starters and even batteries have been upgraded vs typical models and you will not be putting the extra load on them at all. I have not even noticed any change in mileage. I have not observed any drain on my battery. View more reviews...
