Yeah I'll do that and creep up on it. I'll just pull the zero pill out in the second stage retard and drop in a 3*, that will make 7*. Do you think that compression comes into play when considering how much to retard timing?

I havent heard much in relationship to compression and timing with NOS. I ran a 200 shot in my 12.5-1 440 i ran 28 degrees with that set up.
