I just wanted someone to go through the injector tables and see if they seem right. They are 80lbs from corvette injector. He gave me some info for them but from what Ive seen in other tunes its not right. 58PSI

The IFR looks like 80lb/hr @ 43.5 psi scaled up for 58 psi...

e.g. first convert to g/s: 80 * 0.126 = 10.1 g/s; then scale for 58 psi: 10.1 * sqrt(58/43.5) = 11.6 g/s which is what you have.

Ok, how about the rest of the tables. Like Min PW, small PW, Volts ect.

e.g. first convert to g/s: 80 * 0.126 = 10.1 g/s; then scale for 58 psi: 10.1 * sqrt(58/43.5) = 11.6 g/s which is what you have.

damn good thing you have this conversion! it is really a pain in the arse computing this one. thanks buddy! kudos to you for saving lot of my time and preventing me to have a headache! cheers!
