Hello just fitted a new t28 to my gtt and have found its making a whiring noise out the end of my viper induction kit quite loud on tick over seems to get quiter as I rev the engine is this normal or do i have a problem? I did prime the turbo before starting it by cranking engine over with king lead disconnected also it won't boost past a couple of psi even when I adjust bleed valve! could this be down to the actuator not being set correctly have put 140 main jet & 90 air corrector jet into carb at same time if that makes a difference, it is booked into rolling road on wednesday to be set up just want to check It ain't knackered before I waste my money on rollers.
Thanks in advance
