Hey guys. I need a tune. I just got a 2007.5 new body style Crew Cab z71 Vortec Maxx 6.0 truck. I just put on Pacesetter Long tube headers and Y-pipe with 3" exhaust to a Flowmaster, Cold air intake, Texas speed underdrive pulley, 37" tires. I need me a performance tune I can install from HP tuners. Any help would be appreciated. Thanks!

 

37" tires? You need gears more than you need a tune.

 

I feel bad for the tranny.

 

I will have gears later. Just need a tune for now
