Installed EGT and Boost gauge finally. The Autometer Lunar Series is a perfect match for dash lights. I used the pass thru area others have mentioned where you unbolt two bolts, drill, and then use a grommet to protect wires going through the firewall. This turbo runs hot, and is above 900 most of the time, 1000-1200 with normal driving. If you race, tow, or just like to keep track of engine temps, a EGT probe for turbo temps is a must. So far it settles to 800 quickly and then slowly after that. I will probably use anything below 800 as a shut off point.
