Has anyone with the RS2 conversion had fuel delivery problems?  What I
am wondering is whether my replacement fuel pump (Feb. 03) Part No. 8A0
906 091 G is up to the same flow and/or pressure spec's as the original
pumps.  Two out of three of us in Vancouver are having air/fuel ratio
problems at higher boost.  If the recent GP turbos are the same as the
OE RS2 turbos, then its a fuel delivery problem. The two of us both have
had our pumps replaced with the above number.  The third is still
running his OE pump and is not having the same problems we are.

The alternative is  Bosch Motorsport fuel pump 0 580 254 044 but I do
not know how easy these pumps are to get a hold of, the cost and what
has to be done to make it fit in the tank (properly with a working fuel

I look forward to your answers and/or comments.
