Yeah, I was thinking that wasn't too bad of a product, and was thinking about getting one, despite no reviews online. Good thing I stumbles across that!
Glad to hear about the differences in the sensors, I'll have to check and see which use what now.
*Update: looks like only three of the gauges under $200 that I was looking at have 4.9.
The new gen4 PLX, AEM, and...
the glowshift. I never would've guessed glowshift to have some of the better product.
And it looks like summit has changed their gauge. mderoy340's was AEM, but they may not be any more
