It's alright

Haven't noticed any gas milage benefit at all. Gave me a slight bit of torque but that's about it

Range Active Fuel Management Disable Device Review

Reviewed By James A (MONROE, LA) —11/24/2015 1:23 PM

Received the Disable devise about 2 weeks ago. The installation was very easy just plug in. The devise performs as described, waiting to determine fuel economy after several fill ups.

Tuner for 2011 V6 Ford Mustang

Reviewed By Adrian A (EL PASO, TX) Reviewed for a 2011 Ford Mustang —11/24/2015 10:58 AM

This product came promptly and shipped well secured. The instructions were step by step as soon as I plugged in the Tuner. I seldom drive the Mustang since it's my toy, but I did drive it as soon as I put in the Tuner, I can honestly say I saw dramatic horsepower improvement within the 7 miles driven.
