well cant say what works for the sos kit but when I used the rrfpr on my comptech kit my static fuel pressure [vacuum line disconnected] 58-65 psi 6 psi boost with a test pipe and magnaflow mufflers I welded to the stock piping do so searching you will find lots of info my have to google it seems the search engine in the forums isn't what it use to be

Ok thanks for the reply I truly appreciate it so at idle with the vac line disconnected from the rrfpr your fuel pressure gauge read between 58-65?

ya you need to do research on the tuning procedure but basically start at 58psi and go for drive and see were your afr is on a wideband and adjust as needed you may be rich down low but you need and afr of 12.5to1 or richer else you risk hurting your motor

Thanks a bunch guys did some more needed research and understand a few things better.

So the setup is bone stock. I'm going to set the static fuel pressure to 58psi before I do any driving or testing I'm going to install my wideband to monitor afr. I just want to make sure my regulator was set right and what not.

FYI my SOS came set at 50psi. I would start there. I was running really rich at 55psi and ended at 52-53 for a near perfect afr. Make sure you get it on a dyno or have a wideband to set the rrfpr.

If i recall correctly the install guide also says that for the sos rrfpr comes set at 50 psi.

as rtboy10 said pull the vac line of the reg to set static pressure. Also just to make sure you get the best reading off the gauge make sure its liquid filled and blip the throttle by hand a few times after you adjust the reg.

good luck

Awesome thanks a bunch.

Just to be clear it should read around 50psi at static fuel pressure. I have a liquid filled gauge and I plan on only using it to get my fuel pressure set.

I have the static fuel pressure right at about 50-52psi

Now I need to do some research on a wideband install with complete stock exhaust. I've got the wiring down and what not I'm just not sure if the bung should be welded on the oem header or if it could be welded further back on the exhaust. I definitely should have looked into installing a wideband before putting the kit in the car lol. I'm now just wishing I could drive it and be able to safely monitor afr
