yes, maybe MAF connector, or is it a boost leak, so running rich on boost?Last edited by newsh; 14 September 2014, 23:13.

Working afaik, drives great at everything but WOT and idle (tb switch?). Massive difference with MAF plugged in, and unplugged. I have had to unplug the MAF to drive home with a blown boost hose. You can drive it with the MAF unplugged, but not great.Current-2004 Impreza PPP wagon

Hmm, a misfire on high boost would probably feel quite aggresive and likely be accompanied by a pop or bang from the unburnt fuel being chucked down the exhaust.

Not pulled codes tonight. Just drove her home.
I unplugged the n75 for the drive home, and WOT is fine, only 5psi(ish), pulls cleanly.Current-2004 Impreza PPP wagon

Mine is doing a similar thing at the mo, pulls fine at less that WOT but bogs at high boost, I put it down to MAP not being quite right for the injectors. It does run a bit rich on boost and idle is very lean. I need to do a boost leak test again, maybe at 1.5 Bar.

My dad came and gave me a hand today, leak tested to 30psi, we sorted a couple of leaks that only opened up above 25spi, and shut when pressure dropped below 25psi.
More driving and my Dads observation was that is was like it was over carbed; rich at idle, cold starts ok ish, needs throttle to hot start, cruises ok and bogs under WOT.
So stuck the "RS2 replica injector" part numbers in to google
