what is causing this?
its like boost creep, but in reverse. say i put my foot to the floor in 3rd gear, my boost hits 15psi for a second, then settles at 14.5psi. which is fine, it will hold 14.5psi just fine until the engine revs up to about 5k. but from then on it steadily drops to 14, 13.5, 13 psi. maybe even lower if i kept going!
what could it be? cracked wastegate? cracked manifold?
(its the original ct9 by the way)
