My QTP QTEC crapped out after a few months of use. It was at that time that I learned about their 90 day warranty....not exactly my idea of "standing behind a product". I pulled everything apart and learned that the motor wasn't the problem (in my case). It appears that the problem lies in the fact that the sleeve that secures the butterfly valve is ineffective at holding the valve securely.....it took a little work on my part, but I found a fix for that. When the motor finally goes (and I feel confident it will), I'll order a DMH.

I've got a QTP that has worked since I got the car. The previous owner (who worked for QTP) had it installed. No clue how long he had it installed before I bought it but it works great to this day. I've had the car for about 1.5 years with no issues.
