[S/G 386N]

I'd run an in-line in addition to the base. I take the in-line off when I .90 race. I mash the gas so fast when .90 racing the air cylinder can't hold enough pressure to open the carb as fast as my foot would like. Or maybe my carb just doesn't want to open very easily. I have a #1-stop 3 way stop. I use a 2nd stage on it as a rev limiter on the burnout, and not the msd box. It works good, but it doesn't come up on rpms as fast as using the msd as a rev limiter.
