fuel injector ?


ok i got a 97 mustang gt 4.6 with a few bolt ons...75mm tb,100cfm over stock pelenum,90mm lighting maf,cai,ud pulleys,pi cams and intake swap,ad fuel press reg.,tb,and pel. spacers,100hp dry shot of juice,sniper tune,x pipe no cats,1 chamber flows,4.10's,and long tubes soon...thats about it ..my question is about 42lb injectors with this set up...i know there to big...but being i have the juice and the injectors would it be ok to run the 42lbers on my lil 4.6 and not fukk up anything...some people say ya can run them cause the computer only feeds the engine what fuel it needs ,? ,and some say they'll wash out ya cyl. in no time?id use my stock injectors but when i did the pi swap i had 4 of there caps to break on me & i have the 42lbs ?...i can calibrate the injectors with my sniper interface...unless i dont have to being its a 90mm maf meter i have?...idk any feed back would be great...thanks

not without tunning for them you can't.

those ppl that say you will wash out your cylinders are correct.

use them only if you fix them with your sniper.

42#'s are overkill for an N/A set up
even with nitrous.
