The only thing I don't like about the autometer gauge besides the slow boost gauge response is the boost line they give you is very rigid and will kink if you just look at it the wrong way AND they only give you six feet of it. Try putting it onto an A pillar location and six feet is not enough. (I have not found one autometer boost gauge that responds correctly... . checked them when I had them in my truck against an isspro, dipricol, and a caterpillar liquid filled gauge and the autometer was reading zero while the others were at five psi. )
