Thats weird about the AFM, I was under the impression they flowed well and only really need changing when going for big power as the tuning resolution is a better with a Z32 item. Mine's only running about 180@wheels anyway, and I need to get the sus/chassis sorted before I need anymore :(

Mine was maxed a little over 180rwkw as well as another mates.

Perfectly normal. You can tune them up to around 220rwkw odd but its a fairly rough tune. Essentially when the afm max's out you push in enough fuel at that load point to handle the boost being run. So what occurs is say its tuned for 15psi but the afm max's out at 12psi when it hits 12psi it runs the ignition timing and enough fuel for 15psi so not optimal.

But really you never try (thats if you were good enough to be able to do it) to hold 12psi at part throttle with the afm only just maxing out so usually it goes unnoticed. :(

The Z32 allows for a fair bit more scope. Mine went from maxing the std afm out to ~4.2-4.3v on the Z32. Then ~268rwkw was ~4.7volts and now 302rwkw is high 4.9volts on occasions flat 5volts on those cold nights. So nearing its limits again. :S

    • I would be surprised if that wasn't the issue. It's probably telling you, that even if you remove the plastic liner, you may have some other clearance issues that may occur too in some scenarios. IE, tyre to guard. It looks like someone has already rolled the lip, but you may still have issues in the future IE, turning and hitting a bump etc. The fact it changes how bad it makes the noise when you are going backward vs forward is highly indicative that it's the tyre rubbing. They do make a terrible sound, even if you're only pushing a project car that has a liner hanging down on a tyre!   Has the car been lowered? If it has been, what is the measurement from the centre of the wheel hub to the lip of the guard straight up?

    • Mark's a bit smarter than people give him credit... He'd convince the person that is to become dead, to drive him to the forest first. That way his car has no evidence in it, and he's free to dispose of their vehicle permanently how he sees fit too...
    • But if you had to go bury a body in the forest, would you not put that in the boot? Most of them are >=90kg these days.
    • That could easily make a horrible noise. +1 to the benefits of: a) Disclosing all relevant information when asking questions such as these, b) Actually going out and having a look at your own car, seeing as you're the one there, and we're not!
