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..

Stops AFM dead in it's tracks!!!

Reviewed By Daniel J (MAX MEADOWS, VA) Reviewed for a 2007 Chevy Avalanche —3/12/2014 4:54 PM

The Range AFM Disabler instantly killed the AFM in both mine & my youngest son's '07 Avalanches(we bought two)and my oldest son's '08 5.3L Silverado. It has nearly stopped the oil usage in my son's '07 AV and mine putting out a puff of blue exhaust when starting it up cold. The exhausts on all 3 trucks sound much better. None of ours experienced the erratic transmission shifting as some on here have stated in their reviews. MPG in my '07 & son's '08 decreased by 2 to 3 & other son's 07 rose by 2
