hi all.... i have a prob with my 2wd saff. its got a turbo technics t38 and i cant get the boost to go over 25psi. it should run 30 psi and is running air injectors. it runs 25psi with no pre load on the actuator and i was told to raise the boost a little by shortening the actuator arm. i have tried this and it makes no difference at all.. i have checked for air leaks and can find none. any ideas please..?
thanks
