Have had my 99 ecuteked about 2 years ago but this was done on the standard fuel pump, if i was to put a walboro on would i need a map tweek? The car is running about 310 hp.

 

No, the std fuel pressure regualtor will regulate the pressure to the engine.

My mate fitted a Bosch 044 pump (much more flow than a Walbro), rechecked the fuel pressure after the FPR and all was good.

Survived two track days so far on the pump.

 

i agree the boosh motor sport o44 is 1 of the best if not the best on the market its more that capable of running in excess of 8.0bar
