Fuel Presure Problems

[eddiedellz]

Hay! , I just installed a 3" downpipe w/dump and a adjustable fpr im running a
92 thrasher chip. after the fpr and downpipe install the car runs really bad with the presure set at 42 only gets decent if you bump it up to 75 psi :X any suggestions on figureing this out? thanks -Ed

Are you sure the gauge is working properly?
