Reviewed By Sean M (Byron, MI) Reviewed for a 2008 Chevy Silverado —9/21/2009 5:46 PM

Great product, everything worked right out of the box real fun to play around with. 0-60 and quarter mile tests are awesome. makes shift points more crisp and quick. Make sure you do use premium octane (93 or higher) as the extreme setting advances the spark timing and injector timing so agressive that there is a knock and a burn off smell from the converter with lower octane fuel (86 up to 91) that can be avoided by using premium quality fuel

Great product with tons of features and ways to tweak your vehicle. It does seem a little cheaply built, very light and not very heavy...but still does the great work its meant for.

Great Product

Reviewed By Joseph G (Newton, NJ) Reviewed for a 2002 Chevy Silverado —8/19/2009 6:07 AM

I have a 2002 5.3L Chevy Silverado 1500. The HyperPac installed in minutes, plug in with vehicle off, and follow instructions on screen. The transmission firmness option is awesome, and you can feel it immediately. The only issue I had was with 1-2 gear shift RPMs once I programed the truck for "Regular" power tuning, when you romped on it the RPMs would jump and fluctuate but not shift into 2 until you let off the gas and got back on it. I increase the RPM Rev Limiter, and this solved the problem. Everything else is awesome. Great product, would recommend to anyone.
