Not Ranked
I took mine to Keith Craft Motorsports in Plano and had Guru Rob do the dyno tune when the motor had about 300 miles on it.
First pull we got 468 rwhp.
adjust fuel pressure
set timing
change primary and secondary jets (many times)
change air bleeds
he also messed with the power valve ???
dance around and perform his voodoo magic
13 pulls later we got 511 rwhp.
Rob charged $250 and we were on the dyno for about 1:45. By far the cheapest HP I have bought for the car. There is a graph of the last pull in my gallery if you are interested.
