ok i figured this out awhile ago but im gonna post it again with this new info from the injector chart. 390 dsm injectors flow the same as plus 20's. dsm's run fuel pressure @ 43 psi and turbo dodges run @ 55psi if you do some math they flow the same.
first mopar performance +20%
part# lb/hr cc/min psi - lb/hr cc/min psi impendence
P4529495 42 441.4 55 - 37.35 392.6 43 low
390cc/min dsm 89-94 turbo automatic injectors.
they have a grey top and say B390L on the one side.
part# lb/hr cc/min psi - lb/hr cc/min psi impendence
B390L 41.60 436.8 55 - 37.14 390.0 43 low
so in conclusion if you know somebody with these lying around or buy some for the $40 used they go for you can use these as plus 20% injectors.
I also have these in my car with stock fuel pressure and a stock mopar performance sbec and it works fine. alittle rich down low until like 2500 rpm but after that they are great with mods like exhaust and intake and 14 lbs of boost.
