Has anyone here tried tuning for a gen 1 CTD from audiparts4u on eBay? I stumbled on it one night. You have to send him your ECM he puts his tuning on it and sends it back to you. I think it was $350 which is much cheaper than fleece. I know fleece has great products, and I understand good engine tuning is very important. Just wanting to see if anyone has used this guy.
