I have an 02 7.3. Recently had alot of work done...oil pan, water pump, oil cooler, up pipes, manifolds, boots, EBPV delete, turbo rebuild, Banks Bighead, IPR valve, as well as boost, EGT, and trans gauges. Anyway, when in stock mode I have no problem keeping the turbo boost in a safe range and have no turbo surge. However in any other setting like daily driver or fuel supper the turbo spools quite fast and it's no problem to get 30 psi and lots of surge. When I installed the Bighead, I unthreaded it just enough to attach to the waste gate actuator post. But it's my understanding that most folks turn it 5 to 7 revolutions to make the arm shorter. I would like to limit the amount of boost I can build but I thought shortening the arm would do the opposite. Advice?
