Has anyone used the PLX DM-200 OBDII gauge on their truck? It says it's capable or reading EGTs and Boost from the OBDII port. I have finally realized the importance of these gauges, but am hesitant to drill into my manifold to install the EGT sensor. The PLX seems like a good idea if it can read these settings. Any thoughts would be greatly appreciated.

Thanks, Brasso
