Mike asked me to post to fix a log in problem

Like the title says, is there a well known "best" GM tuner in the NorthEast who can do my V? All the "professional" tuners are saying I'm probably gonna need to get a Boost-A-Pump and bigger injectors with the new 2.38" pulley, so the canned tunes aren't gonna be useable for me for too much longer ...

It's the tune not the tuner.
best to update your tuner and reload to truck.

Guys, I just want to help here, The Torque converter and the valve body calibration is set up for 600 lb torque, if you make 900 lb torque the transmisson will fail sooner or later, unless you upgrade the torque converter and valve body to 1000 lb. torque calibration.

I have been building diesel ...
