I know on the ATS setup I have, if you shorten the rod that connects the wastegate valve to the actuator, you can build more boost before the wastegate opens. Do it in small increments though. I shortened my rod 3 turns at a time between test drives until it was where I wanted it.
do u turn the end of the rod to shorten it? and whats the max boost u can get? and is it bad for the engine to turn the boost up? i took a turbo off a 94 and its on my 89 7.3 now if gives some power but i want alil more
i dont need to turn boost up much and no my fuel hasnt been messed with but my friend did it to his and his ran full throttle all the time and blew it up
Before you try to adjust it, take the actuator off, the rod is pinned from the factory, you have to take the end off it and run a tap through it before adjusting it, or you'll break it. But do yourself a favor and get some gauges.
