Is that a "4" or an "A" maybe is this thing adjustable? Was on the car when I got it.

 

looks OEM to me

 

Looks like the 5bar that awe includes in their k04 kits. Dunno why they come with the 5 scratched in, maybe they modify a stock 4bar.

 

I don't think its stock because the car came very modded with a K04 from awe.. it looks like AWe might be scratched into the FPR also. The guy game me all the extra parts and the stock FPR was one of them.

 

Re-read what I wrote above.

 

They scratch a 5 into it because it is a crushed OEM 4 bar FPR to give 5bar of pressure at atmos pressure(vac line off).


Car most likely has a K04-015 on it along with GIAC K04 tuning that uses a 5 bar fpr with stock injectors.

 

Thanks.. Now since then I've upgraded with a FMIC, intake spacer, 310cc injectors, and went PC16.. Should I be swapping this for something else to get the most out of the file?

 

THe PC16 tune calls for a 3 bar fpr with 310cc injectors. But an adjustable fpr works better to get the fuel pressure down to 2.6-2.8 bar.

If you are running a 5 bar with the PC16 tune and 310cc injectors the car should be running very rich.

 

at the moment the car isn't really running at all.. Throwing up codes saying something about the TB. Could my ABS light being on for like a year and having a 5 bar FPR have anything to do with my car only maxing 10 psi boost and bucking like crazy around 5000 rpms?

 

yes because the car would be running way to rich.

Was that with the K04, PC16 and 310cc injectors? If you bought that setup it should have came with a 3 bar fpr.
