well, the point of using race gas is to just have an additional margin of safety at the track. When the car is flat out for 20 minutes in 100 degree weather reaching high temps... that's when it is most prone to knocking. Racegas on an otherwise stock tune is just an additional line of defense. If you guys track the cars, its nice to at least mix some 5 gallons or so of 108 octane gas into your 93. You will end up with about 98 octane and thats pretty good for the car...

Also about the osiris..I used to have a UTEC on my sti and you could literally just switch a little remote dial with numbers on it to switch maps. The osiris system looks pretty cool too, I am going to have that... definitely going to have a track tune, a race gas tune for the track, valet and everyday.

Also...my brake light is turning on whenever I put the clutch in during hard acceleration....like when the cars weight shifts back...almost as though brake fluid is sloshing around, maybe in the reservoir?
