As much as i like gauges to tell you stuff.. (dont get me wrong i've got some defi's)

Don't you think that once the event's happened its too late?

If i had my time again, i'd probably save the dollars and go without gauges. Cause you can;t be looking at your boost gague all the time and once its sitting on say 3 bar... not much you could do either.. 3 bar... 2 seconds.. bang..

Same with knock monitors... by the time its rattled up... well its rattled up.. not much you can do about it..

That said, they do make for pretty lights and all
