Superchips

Superchips Tuners for 2011+ Chevy GMC 6.6L Duramax LML LGH Diesel. Founded in 1983, Superchips was one of the first companies to specialize in tuning vehicles with computer controlled fuel-injection systems. While the company may have started in England, their headquarters is now located in Sanford, Florida and proudly manufactures every single product in the U.S.A. For us, their most popular hand-held tuner has been the Flashpaq. Available for Chevy, Dodge, GMC and Ford; the Flashpaq gives some impressive power gains. It also gives an exclusive 2 year limited powertrain warranty!
