I really want to get my power up a little in the 2000-4000 range pretty quick and cheap. I was thinking of a 50-70 shot to help out. I would probably have a Progressive Controller to engage a shot around 2000 rpm and stop around 4000 so my Vortech can pick up from there with its power band. In other words, the N20 would only be spraying from 2000-4000.
