For what it is worth I have one on my 02 HD and it is great IMO. It blocks the view of the Odometer but that is about it. I dont need to see that anyway! :LOL Easy install.
I did too, but decided on the buying the two seperate and going with the Ford Racing Gauge instead.
Got them both on E-Bay, had both in my hands in 3 days.
It's much nicer in person, I brightened the pic up to see it beter and lost some color and depth.
I personally like this gauge cause it goes to 30, and I happen to have a little over 20lbs of boost.
im glad this thread came up. i just got this settup and i was wondering what line i needed to tap into so that i can have the gauge read boost pressure.
