When you thing that you're finished you realise thats never over...any way i have an 93FD non sequential with pfc-street ported-full exchaust system-intake-and i've just finished a v-mount set up .The car worked great ,has about 350 ps and kicks off with full boost about 10psi at 4500rpm (12psi overboost).A couple months ago when i was cruising and only when i put my foot hard on the pedal with 5th gear (and later on on 4th too)started at that exact4500rpm making a small hasitation (like switching key off )and only the first time if iwould tryied again it was ok.Last days got warst is making it on 3th gear too and not just once but continiusly. I m afraid that an injector might be causing this and that could be quite dangerous for my engine.......please help

 

What is your boost at when this happens? What ECU are you running?

(might be fuel cut?)

 

at that point is about 10-12psi on 4thgear
I have an Apexi PFC
Looks electrical,sorry i dont get it

 

Fuel cut is when the ECU temporarily shuts off the fuel injectors to protect the engine from running lean under boost.
What size injectors are you running?

 

The factory ones, my mechanic insists that they are ok up to 10psi.

 

Sounds about right...the car is overboosting past 12lbs and cutting out. Im Sure its fuel cut

 

Probably Fuel cut.

Double check eccentric shaft sensor signal too.

 

OK fuel cut might be the problem..but why started making it more often ?what is changed ? If this is the case should'nt i expirience the problem from day one?

 

Nice vmount

 

Thank´s mate
