So up until this point I have tuned the car entirely by myself on the street and strip for the past 7 years. It was time to see what the power curve looked like on the dyno so I could fine tune my shift points and see how the powerband really looked. Got in contact with Dave Katz at EFISpecialties and set up a date. First base run on my tune it laid down an impressive 557h.p and 397 ft lbs of torque. After a few pulls Dave turned the turbo up from 38 psi to 43 and tweaked the timing from 7K-9K for optimum power. It made 587hp and 408ft lbs of torque in a 108* heat index. Peak torque was 7300RPM and Peak Power was 8000RPM. We took it all the way to 9K on the pulls and the power curve did not fall off at all. The EVOIII SMIM blew my mind and I am a firm believer on why Curt Brown told me to go with it. We went all the way to 49PSI but the car started losing power so it is most likely a back pressure issue and the BEP .70AR Housing was maxed out.
