The best way to get more power is to get lower gears. Right now with the set up you have
your gear ratio is around 3.10. A set of 4.10 gears will do a world of difference. Way more power.

 

Sorry, but I feel compelled to say that gears don't change the engine's power output. If that is obvious then ok, but please don't say it that way. Say "changing the gears moves the engine rpm into a range where the engine has more power"
And my experience with my tall gearing is that advancing the timing increased the engine torque so my truck would accelerate faster especially at low engine rpms.
Combining lower gears with increased engine torque creates a fun to drive truck.
Peace.

 

i love my super chips , you want to be careful , not to advance your timing too much, you will get ping really bad, and run rich, just curious if your truck has the death flash, if so you will love your truck with superchips, it bypasses it. and you will be amazed on how much power you get. at least i was .
