hi people been having low boost issues for quite some time i havent driven it hard for donkeys years. ive eventually got around to doing something about it. ive tested the base lift on the 31 actuator its running and it starts to open the waste gate at 0.4 psi. from what ive read it should be 0.8 is this where im loosing boost pressure and is this why i cant get the revs up to more than 5.500 rpm i dont have a boost gauge doooow. ive done and checked all the usual guff re wire fuel pump ignition etc thanks
