The Spearco gauge works fine for me....now. It usually sits at 20-22 inches of vacuum at idle and has been going up to around 6 psi of boost when I get on it. Boost comes on Very fast in this car at 2500 rpms. Last year, Josh Brower and I pulled out a grocery bag full of "extra" wiring from various alarms and stereo installations. The car had all kinds of wiring problems, lights that didn't work, accessories that didn't work Everything works now, cept for the cruise, which I will eventually get figured out.
I wanted matching gauges and I wanted something that was backlit green at night to match up with the stock cluster. I am finally getting around to installing the dual guage pod from Lo-tek. Now I have to figure out where I am going to mount the Blitz EBC.
