M50d Fuel Pressure Sensor

Hi guys,

Been gathering as much history and information on my car as I possibly can.

I bought my 335d back in February from
A dealer, it has hybrid turbos and recently discovered also has R90 fuel pump which is great. I managed to track down the previous owner and get as much info from him as possible.

The car was mapped by GKR which is great as they are very well known over here in the UK for these vehicles but it only made 370bhp (ish) according to him, the limiting factor being the fuel rail sensor.

Now if I get the sensor I’m aware the linearisation tables will have to be altered so it runs correctly etc however will the car need tuning again after this or will the car drive okay until I can go and get it tuned?

It will need to be retuned. How far are you going with the build? May need to go ahead and get the rear drv30 as well.

maryjane in all honesty this would probably be it. Basically how it stands already. Hybrids, R90 Pump, Front Mount cooler, XHP map etc, would like to see as much as I safely can with the car, I’d be happy with mid 400s say. Anything higher would be a bonus
