OK so I've bought a mk3 8v GTI, and I'm well aware they're a bit underpowered! In the past I've fitted a decat to an Ibiza GTI with this engine and it did help reducing the engines nasty mid range flat spot, but I'm wondering if theres anything else I can do without breaking the bank to free it up a bit? Its been sat for a while so a good service is in order as well. I've heard of people putting mk2 digifant cams into them as they're not so eco-minded, will this help also?
