I have an 8v '90 GTi with lowered suspension and an induction kit. I'm looking at a performance gain. Bike carbs don't seem wise as it's injected already. A re-bore is probably out of my budget so which way should I go?
ECU mapping is one option the other might be a turbo. Can anyone point me in the way of pros - cons, costs and how to go about it?
Thanks.
