How is the factory
FPR going to be better than the super well constructed SARD
FPR at holding just a 1:1 ratio eg not using the sards ability to increase pressure.
I think that the SARD has got to be better at running just a 1:1 due to superior construction out of billet and higher quality fittings.
When rexes have spontaneously had lean outs who's to say it wasn't the factory
FPR shitting itself.
