Hi All,

I am battling fuel pump (I believe) issues. I ahve replaced the pumps int he tank as well as the filter and sending unit. All coils and plugs have been replaced and one injector was bad (P0203 code).

In any case I am still suffering form the "slump band" in the RPM range while under load (driving). GTS is a 6 speed manual so it's very easy to put the vehicle in the slump.

I hooked it up to the Durametric this morning and took it for a drive. I utilized the logging feature and initiated the following:

1) Fuel Level (53)

2) Pressure Upstream of Throttle Body (902.7 mBar)

3) Fuel High Pressure Set Point (40 BAR)

4) Fuel High PRessure Acutal Value (40 BAR)

Problem is I'm unsure of what the factory spec is for mBAR and BAR pressures. If anyone can let me know it would be greatly appreciated!

Did you ever get the values? I am looking for the correct ones too.
