Hypertech HyperPAC Reviews


Awesome

Reviewed By Tyler G (Chapman, KS) Reviewed for a 2002 GMC Sierra —3/11/2011 10:51 AM

Changed gears and tires and the speedometer was off but the hyperpac put it right back on the money. Didn't notice anything with the added power. But love the gauges an awesome add on to the truck.

Bully Dog Triple Dog GT Tuner (49-State Legal) Reviews


Buy it.

Reviewed By Michael P (Chehalis, WA) Reviewed for a 2006 GMC Sierra —9/23/2016 6:58 AM

After a month of solid research i decided to go with Bully Dog. Very easy install, excellent graphics, produces the best information from your vehicle. The Tow tune turned my sluggish truck into a sports car like feel to the drivetrain, great shifting, and perfect use of the 5.3 power band. If you have the chevy trucks made between 2000 and 2007 (classic) you should have this tuner.
