thinking de cat next maybe?[/QUOTE]

I used to have a connect tdci. Running a tuning box gave better low down power, but a remap gave better overall performance. I think all the tuning box does is increase fuel pressure.

I now have a focus tddi. I blanked the egr, k&n panel filter, decat and remap.
Fmic next I think.
Decat will make it rev much more freely, especially at higher revs.
All you do is take the downpipe off and get a large screwdriver and hammer and bash the cat out. Looks stock for the test then too.
