Jet Performance Module Reviews

Questioning whether to buy it?

Reviewed By Cameron S (PENSACOLA, FL) Reviewed for a 2007 Hummer H3 —11/20/2012 5:55 PM

For GM trucks it's difficult to install due to the small space (30 min. install). After 2 days I noticed performance increase- smoother shifting at different rpm points, more horsepower. DON'T BUY THIS TO SAVE FUEL- it might save you 1 mpg if you're lucky and drive normal, but you'll be wanting to "test" it out so much you'll start loosing fuel mileage. I have this with a JET MAF sensor and a K&N cold air intake all recently installed- total extra mpg w/ everything 3mpg but a big notice in HP.

Jet Performance Programmer Reviews

good value

Reviewed By Bob L (Lewiston, ID) Reviewed for a 2000 Ford F-150 —9/9/2015 8:51 PM

I had used the chip prior, added the programmer and it woke the truck up, quicker, more torque. The chip steadied the PCM at a higher performance level allowing the programmer to boost the output to a higher level than just the chip or programmer alone. Purchased each from AutoAnything and had great experience receiving the items quick, exactly what ordered. Would purchase Jet products again. Tried EDGE and had to keep adjusting the settings to stay in tune where JET has remained in tune.
