Were you also running split fuel rails?

I'll try find it and get a picture, v4's have no gauges etc stock this one is an aftermarket lid. I'd planned on buying a V4 so I got it but didn't end up with enough money from the Pulsar so it's useless to me now lol

I have a carbon one with a moulded hole for a 2 5/8" gauge from a V4 lying around somewhere, did they have the same lid? Back on topic, My V3 STi seems pretty happy on 18, using stock boost solenoid and a 0.9mm mig welding tip lol just has a pod and a turbo-back exhaust. Drops off to 15 at high revs in 3rd gear onwards though so in a few weeks I'll be in the market for a decent EBC

Brap brap brap

Did this, cruised at 60 in 4th gear. CEL is giving me the all clear now (4 long flashes) and it runs very well. Thanks everybody for the input on this

Bought it on 8psi, and it went good. Ran it on 18 for a while went brilliant then put it down to 15 and then I noticed it didn't feel right and did a code check which gave me the codes I mentioned in first post. Still haven't got it back so I can't try anything yet, hopefully tomorrow

The driving part I didn't do, cheers will have give that a go when it comes back from the shop

bump. No ideas?

My ECU is showing fault codes 23 and 44 (44 I'm not concerned about as I'm not using the factory solenoid) Replaced the Air Flow Meter with a second hand unit from a member. left the battery disconnected for ~24hours and the code was still there. Plugged the green and black plugs in, still there. Ran a multi-meter on it, it's getting 12V and the output at idle was reading 0.8V, seemed to increase smoothly with revs, gave it a blast (hard to judge revs under the bonnet) and it went up to 2V, didn't jump around or do anything out of the ordinary. My first Subaru (ex Nissan owner) and first issue with an AFM I've had to deal with, help from this point on would be helpful. Only other thing I can come up with would be a continuity check along the output wire, which I dislike doing
