HI Jast, Chris fitted one of the same guages to mine in the clock space it it does fit nicely, however at the same time he also fitted a Blitz Dual DC turbo timer (follow the link @ http://www.racelogic.co.uk for full specs and pics). I've mounted mine on top of the steering colomn where it's as easy to see as my speedo, It shows current boost, peak boost and has audioble / visual user setable boost limit warning. It's got a load of other features (turbo timer lap timer etc etc) looks nice and gives a good accurate boost reading (checked against the mechanical guage). All in all a nice piece of kit well priced with some usefull safety features. Recomended.
P.S whilst the pictures don't show it, it's also available in black which makes it more discreet when fitted.
