What size injectors would you recomend? Mods in sig. With those pulls on the dyno i was runnin 98% they are the stock size injectors as far as i know. I want some room to upgrade also. A 150 shot will be coming soon. And some boost if i can ever afford it. I was thinking 42#?

With those mods AND a 150 (assuming dry shot since you're talking injector sizes) I think you need to recalculate a little...

^^^ZL1 knows his stuff. He made some very good points when I was debating which injectors to go with. There is a lot of good information in the thread I started a few weeks back on this subject.
For your set-up, the 60#'ers make more sense than with my set-up. But, with the right tune, they are working just fine. Sending enough of a signal at idle to avoid running "rich" (I think...or atleast I've been told by my tuner) Now I have plenty of room to throw some "NOS" (just kidding) at it...lol

edit: Just saw you mentioned "boost" when you can afford it. You'll definitely need the 60#'ers to go that road.

255 LPH, look into Walbro or Racetronix. Might want to get the wiring harness (or something like that).
I just did the 255 LPH a few months back. Went Walbro. I am on my 3rd now after having it replaced again today. Car died on me last night. Not sure if I am just unlucky or if I got stuck in the middle of a "bad" batch. Either way, 255 LPH is what your looking for.
