1996 preface lift sti RA.

I'm coming to the end of a complete engine build and need to get the car MOT'd before being mapped next week. This means it will have to be driven around 30 miles on the standard ecu

The engine has been forged with new up pipe and downpipe, FMIC, K&N and adjustable FPR. I have bigger injectors and walbro to be fitted after the MOT and before the map.

Running on standard 380 injectors with standard fuel pump any ideas what I should set the fuel pressure at?

Thanks

Standard is 3 bar at idle with vac pipe removed from fpr

Thanks If I set the FPR at 3 bar on initial start up I'll be near factory setting?

I could swear I have read somewhere it was 3.8 for 380cc and 4.4 for 440cc... Make shore you uprated that fuel pump before remap

Just ran the car for the first time. FPR was set at 6 bar! Fuel spitting out of the ends of both rails. Set it to 3 and its still pissing out. Gonna replace the O rings tomorrow, fingers crossed.
Other than that it runs superb.

Fuel leak fixed and ran beautifully with grey injectors at 3bar.

Thanks



Fitted yellows and walbro @ 4bar, it now runs like a dog.
