LB7 New Injectors Installed & Misses
 

I just put 15% over injectors in my 2002 lb7 from industrial injection. the install went good there are no leaks and everything seems fine. I have one issue though, the truck will run fine all through the gears if you are wide open or if your just going real easy but in the mid throttle range when your going uphill or sometimes on the level it will miss around 2k rpm. most times it just misses once and shifts down and runs fine but others it will just hang at 2k like its hitting a rev limiter. :argh: any help as to why this is happening would be appriciated thanks

sometimes when you install aftermarket injetors you need to upgrade fuel pumps to keep up with the aftermarket injectors, ive heard of this a few times. i think if you only have 15% over you should be good with just 100gph pump, but for the money might as well get 150gph.
Dont take my word for it, just what my mechanic buddies and me have heard of
