Ectunes spread sheet gave me 69 so that's what I went with. If I change to 72 g/cyl wil read even higher. I'm using all of the injector data and setting from the 50 page long thread on hp tuners site for these injectors. I made due with the info at hand. So again info at hand a ifr of 72 will not help me at this point. Please don't take this the wrong way but it not likey you would waste your hard earned time to give me all of the correct data for these injector which I cant blame you. So unless someone wants to go all the way with short pulse, volts offsetet and all of the other data I'm going with what I can make work and so far that's lowering ifr until I don't hit 2.33g/cyl. Call me a hack or say my tune is a mess, if afr and driveabilty are good what else matters.
There is still something going on here though, as 2.33g/cyl is far more than you are possibly seeing. Based on that number your VE table has to have something around the 115-120% at 4500rpm and 190kPa range. Would that be correct? It would also represent about 925hp at 4500rpm and 85% injector duty cycle, meaning you'd be well over 1khp and your IDC would be well beyond 100% as you get to peak hp. Is your fuel pressure holding?
Is your wideband reading properly?

Okay, so then either fuel pressure is falling off dramatically, causing your VE % to have to be that high to reach the proper AFR, or your wideband is reading inaccurately. It's not physically possible for your engine to have that high of a VE%.

A magnafuel 4301 pump 1500+HP 20–120psi 12A@45psi #8AN in and out roughly from what I have read 2.0gpm@70psi. My system it -8 bulkhead off the bottom back of tank, -8 to the pump, -8 to a y at the back of -10 rails, then trough the rail to the FPR and -6 return to the tank. I run the the stock pump Y'd into the system for out of boost and the big pump kick on with a hobbs switch. I just changed from the big pump being on all the time kicked on through a relay with stock pump, to kicking on straight through a hobbs switch no relay. I bet the hobbs switch cant carrie the amps need trough it. That pump at 80psi should be around 19amps.

I never said that you were a hack their bud nor did I say that your tune was a mess, I havent even seen your tune. Whatever works for you is more power to you.
I was just stating in general that working with incorrect injector while tuning can lead to problems else where because the error gets "baked" into the ve.
As for me if a customer is paying me their hard earned money to do a tune for them I want to make sure it is done as accurately as possible.
Not trying to get into a pissing match with you or anything I was just offering some advice and help, hope you get your issue resolved.
