I did the coating for exhaust manifold and turbo housing...
It does help prevent the heat travelling to radiator,which causes overheating,or aircon shut down...
Please help me..
Normally my boost reading at idle is -0.7.. but nowadays it change to -0.6
why? n the exhaust gas coming out like 'coughing'.. engine like going die when idle but nvr die.. rpm idle normal.
im turbo...
