I have 2014 fiesta ST
MODS:
Airtec stage 2 induction kit
VUDU symposer delete
turbo smart plumb back recirc BOV
when I first start the car and boost the car on 3k revs I get around 15 psi and then the car seems to lose and extreme amount of power and the will boost consistently at 5 psi.
however, even when i am not on boost and put 100% throttle between 1.5k and 3k onwards I got 5psi.
FYI- I have all turbo sounds WHOOSH the lot.


can anyone please help me out as I have pretty much have no boost.

Check boost hoses and clamps* are there any codes?

Are you running stock tune or aftermarket? This sounds like correct behaviour if you have inadvertently switched maps to an eco mode instead of performance. I had similar symptoms and it turned out I had accidentally switched from map slot 1 (93 stage 1) to slot 2 (econo mode) which limits boost in favor of economy. If not that, check hoses and clamps.

Hi Thanks for replying
Yep checked all hoses and clamps all fine, no signs of boost leaks.
And am running Stock tune, no map at the moment.
was think it could be a wastegate issue or boost solenoid issue.
just bought a code reader
