I have new flashpaq tuner, wondering what HP gains for the three different tunes. Also when adjusting tranny are the increased settings ie 2,4 6 psi, above stock or above superchips value? Finally any recommendations for air kit and cat back, interested in something that will help performance but not be too loud. Thanks

The trans pressure is above stock. Sc is the middle of the scale.

91 perf=56hp and 73ftlbs of torque at the wheels
91 tow=48hp and 63.67ftlbs
87 perf=56hp and 72.89ftlbs

I personally use K&N filters and flowmaster mufflers on my BBC 454.

Ron, I have the same 6.0 Y motor and about fell out when I saw the 56HP gains you posted. I have to ask how this number was achieved on this motor only as any other 6.0 only shows gains of 25HP. I am not doubting your numbers but there has to be a reason for the large gains. I am on my way out to find a Superchips programmer.

They have left alot on the table to gain this amount.

TM torque management is a big release of power.
