Do these things work? I see these advertised at most Corvette suppliers. They claim to smooth the air flow and increase power throughout the RPM range. They cost $50, insert ahead of the MAF sensor, and take just minutes to install.
Has anyone tried any of these and noticed any change in power and / or gas mileage? And how about any problems created?

. The Halltech is the other one that I was considering. Heck, maybe I'll get one and try it. If I don't like it, I can do ebay and get a Blackwing, or vice-versa.
