Is a fuel return system needed
I got the g coupe coupe with an ati procharger with exhaust headers and race pipe, walbro 255 fuel pump and 440cc injectors along with the osirus tuner and was pushing 330whp before tune/injectors/pump.
During the tune, We had trouble maxing out the stock Maf sensor so I purchased the HPX MAF sensor.
My question is,
Is a return fuel system needed when using the HPX MAF sensor to get a proper tune? or is that something I could or should install in the future?
Uprev suggested that I install it for proper tuning when using the HPX MAF, but other shop's using the the osirus tuner say that it's not needed.
can anyone help?
thank's
