Thanks !!!
Thanks !!!
I bet it's 4 bar or 60 PSI like the LS2 fuel system.
I have looked around and it seems they are rated for either 3 or 4 bar fuel pressure. Since it's for the LSJ and we have a 4 bar fuel pressure I would say it's for 4 bars.
But yeah make sure you ask this cause it makes a huge difference.

its so they can read higher boost levels.
One bar is used for NA engines. It can only read 14.7 total psi (the atmosphere is 14.7 psi so it technically cant read boost). A two bar reads up to 29.4 psi (14.7 atmospherical pressure and up to 14.7 boost pressure), and three bar reads up to 44.1 total psi (14.7 atmospherical pressure and 29.4 boost pressure).
although this is only on your map sensor and has nothing to do with the actual fuel system, just how much fuel to add...

I jsut got this in email from TJ
just found that one of my old reference guides has incorrect information.
The CORRECT rating for the production LSJ injectors is 4.3 gms/sec. The old
J car injectors are 4.9 gms/sec.

which would make them 34 lb/hr?
Im really interested in your stock injectors as this may be an option for 01-03 GT owners. We have the same injector plugs and the injectors sold in the GP community do not fit 01+ GP's and we need to get different injector clips. If priced right, this may be a worthy upgrade for those looking for bigger injectors.
