🚀 Enhance Your GM Truck's Performance with the Recertified Superchips Flashpaq F5 In-Cab Tuner Review

I first bought 2845 for my 2003 Yukon XL 6.0 engine. My mileage went up 3mpg and power increased significantly. I ride it for performance as a 30-mile one-way daily rider. I also put it on my 2013 LML Duramax. A lot more horsepower on Duramax made a big difference. For a quick increase in mileage and performance without modifications, this product is worth the money. I called Superchips to ask a few questions and had no problem answering all of my questions, which were politely answered.

I have a 2014 GMC Sierra SLT with 37 inch tires. I basically got this for the speedometer recalibration feature, which the tuning shop charged $250 for, so I got this for another $20.

The truck feels more responsive and faster overall. Makes coming up a lot easier on the Autobahn as the truck is just slow at 37s.

I've bought Superchips for a couple of my trucks: 2004 Chevy Duramax, 2007 GMC Duramax, 2004 Dodge Cummins and now my Chevy Suburban 8.1L Gasoline. ALL were amazing! I have had to call support in the past and they have been there, always helpful, always there to help! All of these devices have exceeded my expectations. Raised on my GMC Duramax, with big 37" wide off-road tires, I still got 28mpg on the freeway while doing 65mpg with my cruise control, and this chip turned the powerful engine…
