Quick question. I'm just wanting to confirm that the the stock 350 61lb/hr TBI injectors get that 61lb/hr rating at 12psi and not 13psi?

TBI injectors as they left GM were flowed @ 13 psi , so the 61#/hr would be @ 13 psi .
However there will only be a 2.4#/hr difference (58.6#/hr) if you flowed them @ 12 psi , not much to get worried about IMHO .
This is not applicable to the late 94-95 BBC TBI injectors that were flowed @ 28-32 psi as well as the HD truck and marine units which were also higher pressure.
What are you trying to do ?

Hi Tom,
I've been playing with my 95 Yukon and recently shifted my APU1 back to my 94 G20 van, I was just rechecking the "Injector Flow Rate (TBI lb/hr)" as I've changed the fuel pressure from stock up to 15 psi.
I'd previously adjusted the injector flow rate using the fuel flow calculator, I had previously used 13 psi as my base fuel pressure for stock 61 lb/hr injectors.
I'd since read that 61 lb/hr injectors they were rated at 12 psi, hence my question.
Cheers
Andrew
