Your wastegate is designed to maintain the turbo feed pressure low enough as to not supply so much boost that the cylinders will be overcharged causing an over compression explosion. As for the exhaust leak, your turbo operatesd off of that pressure, if there is a leak than that would be the first place I looked. Also with that big of a truck you need to let that engine breathe and increase the size of the exhaust, intahe and the turbo downpipes.
