HELP! Severe acceleration lag

Not necessarily... The CMC might have still been OK when the CSC was replaced, thus giving you the feeling of a repaired clutch system. However, the CMC is just as old as the original CSC was, and they are both fairly prone to failure. That's why the guys at Z1 and ZSpeed recommend replacing the CMC if you're replacing the CSC. I wouldn't be at all surprised if the CMC finally crapped out a few weeks after the CSC replacement - it certainly wouldn't be the first time its happened to someone on this forum. One guy was on the side of the road bleeding his clutch for over an hour with a buddy before determining that his CMC had failed, and that was just a week after he had the CSC replaced.

Also, the CSC failure will basically strand you - when it goes, it is typically sudden and complete failure. The CMC failure is usually a seal that might not fail completely when it starts to go. The pedal with a failing CMC may still be operable but will be pretty mushy. If this is what you are feeling, it's a pretty good indicator that your CMC is done. Luckily, the CMC is a much easier job (pretty cheap to pay someone and pretty easy to DIY).
