Damn, that impressive! Expecially with no tune! From what they told me, the FMU is do-able but its really junk. They told me they pick up almost 40 rwhp from the tune alone. I differance between the other truck and mine is of course the 5.3 and I have the Dynatech longtube headers. I bet I could damn near make 400 rwhp with a custom tune 42ib injectors and a Walbro 340 fuel pump.

I am also going to try and fabricate so I can still utilize the KN FPIK that I have.
