ok the only time it fired was on the gas in the intake never off of fuel and only reason i wanted to port polish the heads is cause CA emissions heads are a litte more restricting the FE

the industrialinjection pumps that are 42% over or 85% so on what do they do more pressure or more volume of fuel flow?

these % numbers are for flow. this will also translate into an increase in pressure under high loads as it takes flow to create pressure

I talked to industrial injection they said they can take my pump send it off and rebuild it for $720 including new fpr so I think I'll do that I got him to cut the core charge by agreeing to be a rolling billboard by putting a 11" sticker on the back glass something I was planning on anyway

will it protect my new injectors enough? I know injector failure on a lb7 is mostly from poor filtration i just don't wanna risk them you know? I noticed it's a 4 micron filter isn't it the 3 micron range that hurts injectors/CP3?
