Ok.....So far I have on my 2005 Mondeo 115 TDCI.....

Blanked EGR off
De-catted
Evochips Remap

I have also cleaned the EGR out so nice and clean in there, new fuel filter, new OE air filter, and running a load of Millers injection cleaner through, oh and also use Shell V Power diesel.

So.....What next can I do as in trying to release a few more horses, any air box mods? I was thinking about putting a K&N panel filter in but read a normal OE filter is just as good if changed regularly?
