hey anyone know anything about pcm tuning to get more power out of my 96 gmc 2500 with the 7.4l engine or any other things to do to gain some more power

 

You posted this in the wrong section but ill help you out.. you should look into a custom tune.. check out our vendors to the right of the screen.. you have black bear, nelson, and several others.. take your pick.. i went through black bear and he does great work.

 

k thanks and too tell you the truth i dont really even know where i posted it so sorry
