    offboost response td42ti

    After I dyno tuned my car I got more power on boost and slighlty better off boost.
    My mates one is really responsive offboost.
    His one is seriously smooth and responsive off boost.

    Best way to describe it is like a petrol car having its timing advanced.

    My one compared to his feels laggier or retarded?

    We both have
    3 inch turbo back
    bigger intercooler
    Td42t
    Factory Turbo

    13 psi.



    Is there something different his tuner done compared to mine?

    Does advance timing work the same on diesel to petrol cars?
    Was there a fuel setting that his one had adjusted more than mine?

    I noticed there are 3 fuel adjustments?


    - "Max/Main Fuel Screw" at the back of the pump?

    - "No Boost Fuel" screw on the top of the boost compensator?

    - "Spring Tension Screw" under the diaphragm in the boost compensator?


    Is this right?


    I have gotten the tuner to drive it and he reckons my mates one has more pre boost fuel wind in.
    Does that sound right?

    My one hardly smokes. Occasional puff on gear change all hard rev until boost builds up or up a hill initially before boost builds (slight smoke haze trail)
