FMS 0280-150-947 injectors good in this L-98
This L-98 will have a TPIS big mouth manifold, SLP runners, ported plenum, 58mm TB, TPIS long tube headers, TPIS 3 inch catback, vette aluminum heads.Now I've heard these injectors flow 24lbs at 39.18 lbs of fuel pressure and 25.5lbs at 43.5 lbs of fuel pressure. This car has an adjustable pressure regulator would 39.18 lbs a fuel pressure be a good starting point considering the modifications this car will be getting? Oh and this is a 91 corvette I know its not 3rd gen related but it is TPI related question. Some say the car came with 22lbs per hour others say 24lbs per hour. So do I set PSI to 39 first and go 1lb increment and see what the car likes most. And with the mods this car has does it warrant a little bigger injector?

I got FMS A302 24# in my 86. Runs rich at 43#.
From the calibration sheet:
Fuel psi 20# = injector 17#, 30# = 21#, 39# = 24#, 50# = 27#, 60# = 29#.
33# should be close to 22# my Bin is set at 23# factory.
Remember changing the fuel pressure without changing the Bin injector constant will affect AE, PE, open loop, BLM's, and WOT.
