OK so my r32 was on the dyno today and the fuel pressure keeps dropping off now.
Its got a brand new deatschwerks dw300 fuel pump with new filters fitted and the hard wire job done running constant 14.1v now but it won't hold pressure in the higher revs.
Its running standard fuel rail with denso 700cc injectors and a nismo fpr.
My mapper seems to think the pump is faulty and wants me to swap it now for a walbro pump instead.
Can anybody point me in the right direction to solving what is dropping the pressure is it a faulty fuel pump or something else?
