Changed injectors to 42# anything else needed?
Well I am trying to get my old T/A back to the track and with the fuel pressure at 55psi, putting 100 the max in the fuel cells for that rpm range, I am still running out of fuel at 6300rpms,(14.1 afr on dyno) so my 36# are not large enough for the added cubic inches of the new 383 i am just built. I am tuning with tunercats and changed the injector flow rate to 42 and installed the new lucas 42 #'s so is there anyting else I need to change in the tuning?

I am pretty sure that I will have to adjust the fuel trims but I was just making sure there wasn't anything else to change to get started tuning.
Thanks Tony it's great to have the car up and running again but I will turn the fuel pressure down a little since I installed these larger injectors. I won't need that much pressure but I plan on running it in the 48-50psi range so what size injector constant should I put in to get started 44? Also does anybody know how to elimnate the knock sensor completely from the pcm so it can't pull any timing? I had a resistor in the wire from a few yrs back but I would like to do something else. LMK Thanks clint
