I have been having problem with my a/f ratio,it fluctuates a bit,most of time it is alright,but suddenly it will run really rich 10.1,could it be cause by putting a Walbro GSS342 255/l fuel pump,I have read in Japan that you don't use this pump instead use their 190L version,does anyone have experiences like that,I have a turbocharged B6 using a Haltech E6X computer,if any one can help it would be very much appreciated,was going to try and get this sorted out before it goes back to the dyno.

I have read on the miataturbo.net forum a lot about this; the general consensus is that 255l/h is too much fuel for a 1.6L.

Some don't have issues with them though. I'd head to that forum and search; they aren't a nice bunch, but lots of good info.

It is either that or the factory fuel reg can't handle it.
