Adding a HPFP has been considered but a) I shouldnt need it and b) it may not even help
(still cant believe it pulled 320bhp @ prosport!) but time will tell.
Ironically some maps request less fuel pressure (and allow AFR to lean and EGR to raise above recomended limits), so on those I may not have had a problem!

The standard pump will provide 130bar but the problem lies with it not being able to keep up the rail pressure.

Well, I know of several very highly modified GTI's (not Ed30's) of around 300 bhp and they only have the stock fuel pump without any issues. Also VW Racing's track cars which are raw race cars and not used on the road.
[The same cars also don't bother with the S3 intercooler, as do the SEAT race cars have stock intercoolers.]

RR those cars will have a map that caters for the rail pressure being around 110bar that the standard pump can manage.
The pump specific software from APR and Revo calls for 130 bar rail pressure and the standard pump isn't up to the task.

John hasn't got the pump specific software :smiley:

....My understanding was that you could run Revo2+ with a stock FP :confused:
