Now running perfectly.The only negative from me is the gauge housing, there's no mounting hardware so its quite difficult to get it to sit in a bracket securely. I ended up using a few blobs of hot glue.Ready set up and calibrated, just welded the supplied boss into the side of my exhaust, wired a 12v supply to the supplied loom and away you go. ### ⭐⭐⭐⭐⭐ Excelente *by B***A on Reviewed in the United Kingdom on 25 May 2020* Excelente ### ⭐⭐⭐⭐⭐ Excellent *by A***S on Reviewed in the United Kingdom on 19 September 2016* Excellent product and service.
