Bought it for improved towing from my 2011 2500 HD gas Silverado

Reviewed By Rick R (PORT HADLOCK, WA) Reviewed for a 2011 Chevy Silverado —8/9/2018 7:06 AM

The update process and reprogram of the truck was easy smooth and faultless. I haven't towed with it yet but the economy setting has improved my gas milage from 15.0 to 16.9. I guess you can say that the superchip will pay for itself in 30 fillups even if I don't realize the expected towing improvement.

TruXP Xtune Plus

Reviewed By william m (SAN ANTONIO, TX) Reviewed for a 2011 Ford F-350 —8/8/2018 5:16 PM

I received this a few weeks ago. Finally updated the truck. So far only a few shorts trips. initially, the first few shifts seemed harder than normal. However, that seemed to disappear rather quickly. Have not driven enough to see if gas mileage (diesel) will show an appreciable difference.
