TLC to my TSI

[TSOTSI]

I will measure, but saying this they both factory spec VW OEM rims and tyres, Yes i know the incorrect tyre sizes can have issues but i have kept all in spec. i was thinking it could be a carbon build up or over or under fuelling, as said as well the cat has never been opened

The 16 are 245 / 70 / 16
The 19 are 255 / 55 / 19

and did a comparison and there in not much diffs, looks like 1km per hour
