Hi guys looking for abit of advice regarding exhaust back pressure psi? What is normal as mine is currently sitting at 14.4 psi at idle seems very high?
Not something I think most people really look into unless there is a problem.
I will look on TIS and see if it says anything.
Went into vauxhall for a dpf software update they wiped the ecu.... Picked it up yesterday drive less than. A mile and svs came on And went into limp mode!!
