Just bought an 03' Duramax with the Edge Juice w Attitude monitor, 5 inch MRB Exhaust straight from the turbo, with pyrometer and boost A pillar gauges....Workin on purchasing a custom air intake, but in the meantime wondering what everyone does in the truck pulls if you are familiar with the Juice w attitude...Like i said im young and brand new in this sport, so answers for questions such as 4 Hi, or 4 Lo, which setting of the 5 to have the Edge module on, and is it true to not punch the accelerator until you see the weights shifting forward on the sled. Also, any other upgrade recommendations? Thanks guys!! P.S. had this baby on a floor dyno on setting 5---- it read 437 rwhp and 891 lb. ft. torque...I was happy!!
