Minor Threat

I got all excited when I first found Lemmiwinks, going for a DIY management option on a 97 (I think?) A4 1.8T, then I realized is good for pretty much nothing control wise.

Can anyone point me in the right direction for tuning Audi/VW ecu's? That crowd just loves to buy chips...and with all the people making them, it can't be that hard.
