          Please examine the intercooler piping and also make sure that there are no loose vacuum hoses. When under boost, the hose-clamps prevent the hose from expanding due to the air pressure inside the hose. We should not under-estimate the force of 10 psi or more on 3" diameter hoses, what looks OK with engine not tunning may not work under boost conditions.
