hello all, had my car dyno'd and tuned last week, have bosch 044 fuel pump still with standard fuel pressure reg, and was told the the fuel pressure at idle is to high, hence making the car idle really rich and at around 1100rpm. Was told the the standard fuel pressure reg cannot physically bypass enough fuel back to the tank and could be putting excess load on the fuel pump at idle.

I am running,

Safc, bosch 44 fuel pump, 11psi boost, front mount.

Was interested if anyone else running similar setups to this has an aftermarket fuel pressure reg, if so what brand? did u install it yourself and if anyone has any idea wat the correct fuel pressure should b in the fuel rail at idle?

Any help/feedback would be greatly appresiated

(have posted in mechanical section but fast feed back tends to happen here)

      Who has a Infiniti Q60, Q50 (V37)?

      Yep, it was only an option on the Q50 Hybrid.  Same in Japan as far as I know. And doesn't use a centre diff like the Suby's do, so not the same as the WRX.  But it also isn't a reactive AWD like other Nissan AWD vehicles are, eg. Murano/Xtrail/etc.

      You should have got a Maine Coone then. Only thing is they're big. But so cool, and just like a dog. Or, just get yourself a high performance dog. That'll teach you for wanting Parkour indoors 😛

      Are you thinking of Bens R32? I don't remember if his went through the bonnet itself, but it went through the chassis rail. Brad (RISKIN) bought it, and turned it into a track car. It's funny how anti people are of Jim Berry now. I remember when I pulled mine out (during an engine change) and inspected it and found it cracking badly. At that point in time so many people were even on SAU, were so pro Jim Berry, and that was after Bens GTR exploded his quite publically.

      That's one of the reasons I got that breed, they look weird, the other reasons are they small, they are very vocal, and run around like they are on crack, I didn't want a breed that just sits around, these two are like kids on red cordial  My daughter has one, and it's a laugh riot, constantly doing Parkour around the house, sits on her shoulder, plays catch, and constantly runs around the house taking turns chasing the dog around, her Bermese though, just lays around with constant bitch face, and just looks on in utter disgust at the cat and dog playing together

      I'm getting PTSD flashbacks seeing that name again.  With my turbo swift, I got 1,500km of street use on a Jim Berry clutch before it exploded and took out my input shaft with it.
