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

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.
