    Hi.

    I got the map done locally stage 3 with my hybrid turbo fmi tip injectors decat etc not paid for until i sort the issue out

    When i first try to put the pedal down it goes like a train at 20psi a couple of times then goes into soft limp mode and runs at 5psi for the rest of te journey.

    On the computer it shows an overboost error

    Any ideas?

    Removing the hose from n75 to wg, it is exactly the same.
    Removing the plug for n75 however makes it stay in soft limp and 5psi

    Sounds like the guy did not map the car correctly and the map sensor is picking up more boost then was programmed. I would suggest a EBC or MBC to turn down the boost.
