88 workcar,
I must be part of the minority . My S trimed engine ran a 10.13@135 with base timing and a BTM . No chip ! Idled fine. Don't get all caught up in chips/fmu's and everything. I know quite a few guys who run and have ran up to 12lbs of boost with 30lb injectors. Although 42's are nice, they usually reqire a chip because the car just won't idle with them. If I were you, I would make sure the ProM 77 is calabrated for a supercharger. ( That makes it 10% richer everywhere but idle. ) Put the 30's in, base fuel pressure at 45lbs, get a big fuel pump. Then, first thing, put it on a dyno with a wideband and see where you are at. If you are interested in how I ran my timing, let me know, I will tell you what and where I had everything.
Tim
