After replacing my turbo (still original size), I finally fitted up my boost controller to the my 99 GU. Prior to the controller, my boost was sitting nice and even at 5psi crusing in 5th @100kmh, and it would peak at 9.5-10psi under full load. Using the controller from Mudski, I wound the controller to it's 1/2-way setting and installed it. Cruising now in 5th @100kmh it sits around 8psi (give or take a little), medium load/acceleration it jumps right away to 10-11psi, and under full load climbing a hill it peaked at 15psi.
Are these parameters safe for extended use with the RD28Ti? What would be some of the downsides to running increased boost over long periods of time? The Patrol definitely seems a bit more responsive of the start - it could easily break traction at the rear wheels when accelerating empty from a dead stop. I know I haven't cranked up the boost a whole lot. I don't want a race car, just a bit more acceleration and power to make it easier to drive.
