I had some kind of weird falling out with my tuner and was looking around for someone to finally get my built motor tuned. Someone I trust called me, made a recommendation and set me up. The only down side was it was 6 hours away, but what the heck, I needed tuning bad.
Drove down this past Friday to Boynton Beach FL and spent the night. Drove over to the speed shop Saturday morning and met up with the owner. The tuner showed up on his Yamaha sport bike. Anyway, I told the tuner I didn't want to drive 6 hours from home only to have my car blow up on the dyno so he tuned for safe power.
Tuned first for 93 octane - (R+M)/2. Results - 650 rear wheel hp and 648 rear wheel torque. Then they drained the remaining two gallons of 93 octane from the gas tank and poured in some C16 (117 Octane). Results - 690 hp and 669 torque.
Put the two gallons back in that we drained, loaded the 93 octane tune, hand shakes all around and I was gone. Opened it up on the turnpike through the first two gears (Florida Highway Patrol was everywhere) and, whoa - I've felt power before, but the only way I know to describe the difference is that I've never felt the power come on as smooth. When I got home I took my wife for a spin and opened it up through a couple of gears. She commented on how smooth the car was. Damn, even my wife noticed.
Can't wait to take her to the track. I'll definitely run the race gas tune. :)
