Recommended Posts

hello, im running 1 bar of booast on the ct9 turbo and ive set my fuel pressure reg to 3 bar and its making a really high pitched noise at lower revs. wen i lower the fuel pressure a bit it goes away! is this the fuel pump or injecters cant keep up?? ive been told the standerd pump can go to 3.2 bar.

i don really want to put the fuel pressure down as ive uped the booast.

thanks for any help.

if you have stock Pump and stock injecotors then it shouldnt make anymore noise that before! Id check to make sure your FPR is set up correctly.
