I love my Stack gauges. I wanted everything to match. And they have programmable warnings that change the gauge color, so you don't even have to be looking at it. If something goes outside of set specs, you'll notice it out of the corner of your eye.

 

Run 3 AEM gauges and love them.

 

bump for some more opinions. Trying to decide myself...

 

3 years and zero issues with my aem gauges. The black face plates look sweet too. 2 thumbs up.

 

I guess im narrowed down to STRI & Defi. Thanks guys!
