Sold my PLX R-500 to a good friend for his project rb26 s14 and just ordered up my new PLX DM-100 with the Wideband and EGT sensor modules. I've always loved my R-500 super legit, tons of features, but it was just to bulky. I was going to opt for the 60mm DM-200 gauge from PLX but I figure a nice small 52mm would be better and give me more areas to mount it. Should be here in a week or so. Will update as soon as I get it.
