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..

Easy to update. Easy to download programs. The performance tune adds 16 horsepower, according to Superchips testing. Numerous programs to choose from. 91 octane performance, 87 octane performance, gas mileage tune, factory upgrade, stock.... Excellent price.
