I am in all honesty pretty ignorant when it comes to fuel injection, but that sounds pretty much like enough of a change to warrent getting more hard core units. I'd definetely go with 30s or better. But I could be wrong. LEt us know how it turns out, I am especially curious.

I can pm u a scan of a good write up out of a book I have for injector selection, a little math involved. I would say 30-42 lbhr injectors, cant really have too big of injectors (to a point), pulse width can be changed w/ tuning, and 255lph or bigger walbro pump.

My #'s in sig and with stock injectors with a lot of hp tuners data logging my injectors average 94% duty cycle, thats why I went with Racetronics 37lb injectors for my 100 dry shot.
