I have a 2008 LS3 Corvette with a A&A supercharger kit and 60lb injectors at 43.5 psi. does any one have ideas on what flow rate to put in for the flow rate vs pressure delta?
i have looked everywhere and cannot find anything, a 06 and '11 tune with the same injectors is different and i cannot figure out what to put in to the table since it will not let me go above 63 psi. :shrug:
Please help this car is supposed to leave today.
thanks
I though they ran at 4 bar or 58 psi like the other LS engines?
yeah they do but the injectors are rated at 43.5 meaning that at 58 psi they should be about a 70lb injector. but i could be wrong
im sorry up there where it says go above 63 psi i meant lb/hr
Ok so i have the injector right i think. but now at WOT at like 5,000 RPM the car goes lean like way lean. and on the log the MAP is 120 kpa and wont go any higher and the injector duty cycle is 100% any thoughts??:shrug:

Log your fuel rail pressure and see if it tanks.
log it on the scanner? tried that it never changes
No, put a gauge on the rail (long hose) and tape it to the windshield. Then see if the FP is dropping at WOT.
ok checked it with a manual gauge and it drops pressure for sure. i wonder if my boost a pump is not working
