chucked a map on the 200k passat i got off chuff
it did traumatise the ratteling wastegate a bit to much tho, found the valve head wedged in the exhaust turbine. quite how it managed to get there i failed to work out, 2nd hand turbos are cheep enough rebuild kits are cheep enough as well, ether rebuild it if suspect it or get a 2nd hand one and rebuild that.
as for clutches if a map kills it it was on its way out anyway
