Superchips 3571 Flashcal F5 Tuner

I installed the cortex superchips programmer on my 2005 gmc Sierra. I am very pleased with the results. It boosted my gas mileage about 3 miles per gallon. I could also see a boost in the horse power immediately.

Don't settle for the first tuner that comes along. Tune like a professional, and open up your engine unlike ever before, with a Superchips Cortex Programmer. Backed by a 1-Year Warranty on the programmer and a Two-Year Powertrain Warranty for your vehicle.

Superchips - Automotive Performance Tuning

At 4-Wheel & Off-Road we enjoy testing both new and existing products, especially when there are promises of power and fuel economy gains. So to try our hand at getting a little more out of our Cummins diesel–equipped ’06 Dodge Ram 2500 4x4, we ordered up a Superchips Flashpaq programmer. With the help of the high-end car tuners at National Speed in Wilmington, North Carolina, we put the Flashpaq to the test by strapping our 3⁄4-ton onto their all-wheel DynoJet diagnostics machine. To learn the most about our tuning tool, we tested the truck in stock, tow, and performance settings both on and off of the dyno. Want know how things added up? Read on.
