    My S3 boosts upto a maximum of 21psi so 18psi sounds about right on a K03s. Boost is not everything! Could be 200-210 I guess but wants to go on a rolling road to be sure.

    I'd say it's been mapped.

    Ooo really , what would you say would be good boost pressure ? An would it be worth adjusting the actuator?

    18psi-20psi sounds right to me.

    sensible boost will depend on (a) the mapper, and (b) the intercooling ability

    eg: polo Gti I did on Friday... 1bar of boost only on its k03s on stock smic, 65'c intake temps..

    26 psi is to high for a ko4, it will be on meltdown

    Owch... uber spike of boost

    Not ideal!

    gets things too hot too soon..... It will make more power from less boost... as it will reward for running cooler cyl temps
