I got the EVO based upon how they look & all digital w/ great startup & I think Steve from Canada recommended them. They work fine but there are a couple issues that anybody buying them needs to be aware of. Sunlight glare makes them hard to read. Have to keep sunroof lid closed if really want to see them good. Also their ad says that during day can have one color at night w/lights on another color. Well that won't work with our electrical system, so have to chose one or the other. So if had to do over again would get a gauge that's a combo digital/analog. I know they are out there. Gauges I have, which i still like combo are boost, egt, & wideband afr.
PS: going to all show i've gone to this year & seen guages on lots of cars, Chris's is still the best design for a car that i've seen. Absolutely nobody thinks it's not a factory option.
