Jet Performance Module Reviews


Better than expected

Reviewed By John J (LEXINGTON, KY) Reviewed for a 2004 Ford Escape —7/24/2014 5:33 AM

I was skeptical about getting one of these. After talking with about 3 or 4 guys that have one in their vehicle, I decided to dole out the $200+ to get this. Needless to say, I was amazed in the performance. First thing I noticed was how sensitive the gas pedal was, took a while to get used to. I wanted to know how much it would increase my gas mileage, so I took averages (3 fill-ups) of MPG before and after my second fill up afterwards I had noticed about a 2.5-3 MPG increase. Worth it!

Hypertech Speedometer Calibrator Reviews


Drano

Reviewed By Kerry D (WHITEFISH, MT) Reviewed for a 2006 Chevy Silverado —7/22/2014 5:11 AM

Very satisfied. The Hypertech Speedometer Calibrator arrived quickly and was very easy to use. The instructions were clear and walked me through the programming process smoothly. I tracked my speedometer accuracy with my GPS and before calibrating it it was off 15%, which meant I was traveling 69 mph when my speedometer dispayed 60 mph. After programming with the Hypertech, the speedometer is spot-on. I can also easily reprogram when I install my smaller diameter winter tires.

Range Active Fuel Management Disable Device Reviews


Not worth the money

Reviewed By Alan M (Kalamazoo, MI) Reviewed for a 2007 Chevy Avalanche —7/20/2014 5:15 PM

I haven't noticed any change in the performance of my truck. The range device does disable the active fuel management system like it says it will. I don't think this device is worth the almost 200.00 dollars I paid for it.
