FYI for those interested in a multifunction gauge. I installed the Perfect Tuning gauge using the gauge pod for 1994-2002 Mustang (GlowShift GS-107). Very easy install but the pod needs to be cut to accommodate the larger diameter of the gauge and the included gauge hold-down required a little modification to fit within the pod. The gauge is well built (aluminum) and has lots of options, including flashing when limits are reached (RPM, boost, temp, etc.).
