Anyone know anything about this ecu chip?

These two "work" by lying to the ECU about the air temperature coming into the intake. I think they're both total rubbish. Even if not, their claims are wildly exaggerated.

This one I'm not certain about, but I believe it does the same thing except through the OBDII diagnostic port. Again, probably rubbish and definitely not remotely like the claims they make.

Lying snake-oil salesmen all, as far as I'm concerned.
