soz if this has been coverd before i think i am suffering from fuel cut although i have a fuel cut defender fitted,has been on the car for about 2 years never had a problem until recently
its fine on the flat but if you go to overtake or under load up hill it seems to suffer then any ideas folks cause i am stumped
thanks in advance jaymes

 

little bit more info required such as year of car,mods done to car,what fuel cut level the FCD is set at etc.
Has the weather been a lot colder where you are?

 

yep sorry was a bit vague its a my96wrx all ive done to it is full system headers back,air filter,fuel pump,boost raised a little and a fcd fitted the boost was raised and fcd fitted at the same time both turosmart parts fitted at a tuner in plymouth has been running like that for about two years no probs
it has got a little colder within the last couple of days although it was warmer when it done it first
have put a different maf senser on and changed the fuel filter but it still does it

do you have a boost gauge fitted? and how was the boost raised? if by a manual boost controller then it might need a clean and re adjust.i think 7 on the hks fcd was the recommended one for the impreza, not 100% on that tho
