Hi

Need info in this one.My friend go with the cobra for a ride with me and i have the diablo in my hands.Its fuel pressure in the diablo give me 39psi but the gauge in the dash (brand new) tell me 29psi in idle.Its a difference of 10psi it is possible.Did he need install a fuel pressure regulator???

if the car is running OK, then the gauge is probably the one at fault

it is supposed to be 39 when not in boost
