Hi Lads
I need help, got on water today, started down river gave it full throttle up it went revs up at 7500-7600, then it just felt like like it was losing boost?
dropped back to 6800 then 5800. no faster.
got home checked compression 140psi on both ,oil ok, coolant ok.
plugs very sooty black.
checked all turbo hoses, all looked ok.
so now i am lost??
any ideas??
oh and there was a new solenoid fitted, the one on top of the turbo, and a remapped ECU.
