Get away with 38lb injectors on 8# ATI no FMU?

I know most go 42lb injectors to eliminate the FMU on the ATI procharger. Think 38Lb would do the trick? Came across a good deal on a set.

Adam,
I wouldn't trust it but it's up to you.

Adam,

These were my injectors and they behaved just fine at 476rwhp and making 6psi. The only reason I sold them to Adam is because they won't support 500+rwhp and I upgraded to 50# injectors.

I too had an FMU and had fueling issues. These 38s were the remedy and did their job well :)

I run 30's....100 percent duty cycle at WOT...Briefly...
455 RWHP, 447RWTQ....58 psi FP at idle, no fmu....
I'm programmed that way, "safe", is a relative term...No knock, showing 900's on my o2's....
Hoping to get my larger (proper sized) injector's soon, but this does work for now...

I'm doing the same thing. 38# injectors, 7# of boost, with no problems.
