What is the deal with lock-up vs. non lock-up TCs. I'm very ignorant on this issue and would like more info. Advantages/ Dis-advantages.

I can't add much to this... Just that a lock-up is good for a daily driver, keeps the rpms down a bit, better mileage. But it's a weak link for high hp too. I would think you'd have to tune it out, without a lock-up converter, to keep from setting codes.
