1st-3rd burnout manual mode tune 4 On 2007 GMC Sierra 2500 classic.-
Mods:
Mike L built trans, goerend triple disc. HSP full grey powder coated EGR delete with all hot and cold side piping, matching Y-bridge, HSP uppipes, AD165 4g, EFI ecm/tcm tuned by Idaho Rob. Fuel rail ported and shimmed. It has a Grizzly locker in the rear instead of the factory G80 which turned out to be a dumbass decision for a street truck....the diff was unlocking around corners with barely any harmonics and working great but the truck developed extremely bad wheel hop under throttle due to the way the locker applies power. I ordered a set of traction bars from Longhorn Fab (the professional series which is way beefier NBD) and corrected the wheel hop. An S&B intake, ppe t304 stainless downpipe, 5" magnaflow t409 inch straight piped with 18"x7" axle dump MBRP black tip. 305/50r20 Nitto 420s on Mickey Thompson Deegan series rims.....merchant pump rub kit, fox 2.0s x4, cognito UCAs, kryptonite DG tie rods, the DG pitman arm/idler welded in braces. HD sway bar links Redhead steering pump (life changer). That front end setup was overkill for the power I was making at the time (569whp/1207ft lbs) but I wanted room to grow and also avoid becoming a meme when my factory tie rods grenade on camera and the truck goes pigeon toed.
