    Well I run 30# injectors with my SN89 making 6-7# boost with a Moates chip/tune. My suggestion would be just to start with 42# injectors then you'll have enough injector if you ever increase boost (kinda wish I did that). Keep in mind you'll need something to increase fuel pressure under boost, either an FMU or better yet get a chip/tune for safe a/f ratio.
