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!

Jet Performance Programmer Reviews


Added automotive performance in a box

Reviewed By victor g (MESA, AZ) Reviewed for a 2008 Chevy Avalanche —6/8/2014 2:45 AM

I praise Autoanything for the great prices for name brand products they offer. The Jet Performance Programmer did everything advertised. I am happy with the results. Autoanything needs to speak to its vendors who apparently move its defective product to Autoanything making Autoanything bad. I've had to send back three items to Autoanything because of bad poor quality or workmanship...not the fault of Autoanything.... Autoanything kept its promise.. Went extra mile of replacing every item..
