Before I got booted off CGP someone had posted about a new company making gauges that were out of this world and not a whole lot more expensive than Autometer. There were a cross between Autometer and the plx gauges mentioned above.
If anyone knows of which gauges I am talking about please PM me the link to them. The reason I mention this is because I remember thinking, after reading about them and their sensors, they should be highly accurate gauges.
Anyway, if anyone has knows which ones Im talking about, send me the link please. I had planned on getting a couple and now I cant find the website anymore.
