"I had no problems installing Superchips. I have seen a marked improvement in my gas mileage around town and have not been out on the road to check its performance in that situation. I'm very pleased with the product as of now. Jeff Glenn"
"The ease of installation was better than what I had anticipated. The programmer housing was an exact match to my dashboard, and the appearance of the unit looked factory installed. I have only had the programmer for a short while, but enjoy the fuel savings already."
"Perfect, love it!"
"New product from DiabloSport is just amazing. I used to have the Predator tuner, but this took my car to a whole new level! Not only is it sleek and more modern than Predator, it is very easy to use and turns your car into a beast!"
"Very easy to install and very easy to use. I really like the increased power and fill of the torque. "
