That should tell you something. The autotech sticks just don't have as much lift as the other manufacturers cams... otherwise you would need the valve springs to cope with the increased lift at higher rpm's. As for the TT valve springs failing, I can't believe they sell those things. Those are not "high-rev" valve springs by any means. They are stock VW diesel valve springs.. and diesels physically don't rev above 5 grand- the physics of a diesel motor causes it to stop making power at about 4-5k. I'm really surprised that tt still sells those things.
