Dayum I took a ride last night with an owner of a Diesel works performance shop last night and whoa hold on to the dash, his truck was pretty kickass.... He has an 04 QC just like I do except being owner of a shop he has all the toys. full intake including new turbo tube, bully dog puter box, 4" exhaust and the pac brake. Full set of gauges sit under the radio where the "crap" slot was in the dash. turbo boost, pyrometer and I forget the third gauge. Talk about being pushed into the seat, made me start ordering stuff for my rig. just ordered 4" Turbo back magnaflow system and think I'll wait a pay period b4 buying the bully dog, I already modified the turbo silencer inlet so thats clean, riding on H2 tires/rims and will be talking to dealer tomorrow about the recalibration if can be done to reset the speedo.
