Wow I just found this thread guys. Very interesting. I have never heard mention of any 'finns' however in my reading today it seems they are mentioned a few times in relation to upping horsepower out of these engines. Where is there more info on the mods they have done, or parts available? Unfortunately I only speak english.
I have the speedtuning chip and subsequently have an offensive amount of smoke under WOT, even with a new air filter. It should be noted that I am under slightly more load though, due to reducing my overall gear ratio with the larger diameter tire/wheel combo I have, which will cause more smoke. In any case, I'm also interested in hearing about any info on how much the stock turbo can take and what it makes now psi wise. Are there bolt in kits for larger intercoolers, turbos, or air intakes? Info please!
