Builder of OVERKILL!!
I finally got tune time with Steve Petty, he changed my tune around and with bigger injectors, bigger turbo and Methanol injection since my last tune, I made 924rwhp and 986rwtq. The better numbers came with much less boost, 18.6 psi vs 21.4 psi with my old set-up (850rwhp/ 889rwtq). The power was with mostly 93 octane with only 2 gallons of VP 109 race gas added to a little under half a tank, for safety. We did not go any farther with out more race gas. With the higher power levels in the lower gears, I found the end of all my great traction, if I leave it at this power level I would not be able to put the peddle to the floor until 3rd gear. My lowest boost setting was 13 psi and gave my 834rwhp, I plan on backing down a waste gate spring to lower the boost for pump gas only for the street. With my next level down spring I should still be around 750-760rwhp and can still turn it up to 2 1/2 times the spring pressure with race gas. I will post a dyno video.
