First of all I was impressed with how quick it arrived, the experience in using it!I after installing it and driving it I was totally impressed with the acceleration especially from 20 mph onward, the truck acted like it had a blower on it, and when I hooked up my toyhauler which was the main reason for getting the chip, I was very impressed by how it seemed like my truck doesn't have to work as hard pulling,didn't help mileage empty or pulling I have 01 GMC 6.0 200600

This product do what they claim it does. I just had a little issue first when trying to install it but after contacting Superchips directly they had an update that fix the issue. Truck is now running a lot better.

Superchips Flashpaq F5 Tuner Reviews


Works great

Reviewed By Eric I (Spokane, WA) Reviewed for a 2006 Chevy Avalanche —7/13/2016 7:37 AM

After receiving the tuner, I updated through "ignition". Plugged in to my port, and could only get 12% download from stock settings. Called Superchips, got 5 more updates, had to unplug 2 radio fuses,and worked great. 3 to 4 mpg better on economy setting without losing power. Am going to try towing mode, and hope for good results as well. Good product, very good customer support!
