yes! contact PCMforless, westers, zippy, or any other computer tuning company. The handheld programmers are worthless for power. I am very pleased with my PCMforless tune done by Bryan H. You will have to take out your computer and send it to them or buy a core and do that. They will optomize any mods you have.....CAI, catback, long tube headers, camshaft, shift kit, trans line pressure.....anything. Or just advance timeing, remove some TM, and raise the line pressure in your stock truck. I have the basic CAI, cat back, and shift kit, premium fuel tune. 100% of torque management removed on my 06' vortec max truck. Flat out hauls azz and pulls sooooo hard up high in the rpms. You will love how a custom tune will wake up your motor. Very cool stuff.
