    take it back to the tuner for investigation. you have a totally custom machine and its obviously not right.

    whether its the tune or something mechanical thats the place you need to start.

    you risk killing that built motor if its leaning on boost or worse.

    I did it with richard and jason in christchurch, they seem to know you. Jasons comming up in decemeber so will have a chat to him when he comes to welly.

  2. idle pressure is 43.5 i was meaning when -20psi boost idle.

    Its actually a subaru b4, just seemed easier to describe it as a v7.. haha

    Im in Wellnigton.

    2.5L forged cp pisonts, datrton sleaves, eagles rods.

    v7 sti avcs heads with some work done to them

    bosch 044 fuel pump with surge tank

    walbro 255 in tank pump

    id1000 injectors

    Holset hx40 turbo

    NGK 7 heat spark plugs.

    Aeromotive regulator 1:1 ratio

  3. Ive just got v7 which has been completely rebuilt, It was running fine for a month or so and has now started stuttering out of the blue, usually when boosting over 10 psi. It also likes stalling after driving it hard and being stopped at the lights.

    First off I replaced the fuel pressure regulator to a high end aeromotive as the previouss one was reading 43psi even with -20 psi boost through it.

    The new reg now reads around 37 psi when at idle which seems more promising. It now seems to stutter a lot less and idle a bit smoother (previously it was hunting all over the show until it stalled).

    This hasnt fixed the problem, so now ive put new spark plugs in it, still the same.

    What ive noticed is that when setting the pressure on the regulator it only holds pressure for a second. I literally had to get some one to sit in the car to keep priming the fuel pumps so i could set the pressure before it would fall to 0 psi.

    So is this a problem? As when i turn off the car Im mmedialtely reading 0 psi fuel pressure on the regulator, is it because im running a surge tank?

    Sorry I should of said my mate works as a mechanic, the guy comes to his work to do the certs.

    I like the idea of the truck with all the set up in it, now that would be pretty cool alright

    Who\'s the guy that actually does it?

  5. My b4 is stuttering around 12 psi and stalling at idle I\'ve changed the spark plugs and checked the fuel pressure reg and its still doing it.

    The exhaust smells a bit like fuel so I\'m wandering if its a coilpack itself they\'ve all done 160000km.

    Anyone around welly have 1 I could borrow for the weekend to test my theory.

  6. Hey just wondering if anyone can recommend a quiet muffler for a straight 3" with only one resonator.

    Im currently using a 3" trademe muffer and it is redonculously loud, im looking at getting an HKS Hi power muffler, is there anything quieter than that?
