The xrT is making less boost than it should, and it feels less powerful than it used to. Under normal conditions, its usually 2-3psi under what it should be producing. Eg, on stock 6psi, it peaks at 4 and trails down to 3. On my 8psi it peaks at 6 and trails to 5. On 10psi, doesn't get past 8. Now it used to hit right on the money on all tunes all day everyday, so its not the tunes. Sometimes on stock tune its flat out making 3psi.... Obviously somethings up, after a good boost solenoid clean it improved somewhat, mainly the way it brings on boost. but the figures are still down. So I need to check for boost leaks, I figure the below is what I need to check, but please add what I have missed. Also, any ideas on what clamps to buy to replace them all? replace all hose clamps Inlet manifold bolts Exhaust manifold bolts Turbo bolts check hoses for cracks anything I am missing?
