Please - no comments from diesel owners, but how smokey is your mk5?
I know the ED30 runs a bit rich, as the carbon on the exhaust and tailgate really shows on mine, and it isn't mapped.
Is this the same on the GTI?
Only asking as I am sometimes surprised by the smoke mine puts out on WOT. Hope it isn't a sign of anything sinister, but it is mostly sooty smoke. It is run on Optimax, so the petrol should be good.
Does the smoking get noticeably worse if remapped?
