fast injector part numbers
so i bought a set of fast 57 lb/hr injectors from a guy on here and in the tuning process we are having to pull so much fuel out to get it to run that he thinks i may have been screwed over. so with that said i pulled an injector and got this number 80507 off the side. can anyone confirm this number belongs to a 57 lb/hr injector so we can tune the correct numbers in.
thanks
thanks

Do the injectors say "FAST" on them? Could it be "30507"?? (1) LS3, L99, L76, LS7 Type 50lb/hr Injector Fuelairspark.com
One problem with tuning the FAST injectors is that very little tuning data exists for them... Sorry you're having troubles.

i called FAST and what do you know... they have no clue what they are either. so from what i have gathered my lsxrt intake is garbage because its warped on the intake seals and they build products without part numbers to identify them.

no i had to pay for a new lower intake. 250 later and it seals with no vacuum leaks. had to coat the upper plastic seal with a large amount of rtv. but the thing that is bothering me is that these injectors are acting like 33lb/hr because of all the fuel we are having to pull out of the tables to get this truck to run.

i have a set of the 30507 and they are the shorties. this number doesnt show on the injectors, its different, luckly i kept the info and package when i got them. wow that number you mentioned doesnt even exsist ( terrible ) glad i never invested in that intake, i knew it was useless and trouble before it came out.
sorry not much help, but you could send it to FIC and let them flow test the injectors, this will at lease let you know what you have ?

finally got ahold of someone from FAST who has an idea of whats going on. these injectors are factory Delphi injectors that were modded by FAST. they are in fact 57 lb/hr injectors. now to find the proper injector data for Nick at Newtech Performance so he can get this pig running so i can giver her a break in. ill get video up on my build thread once hes done on friday.
