First, the primary thing that anyone can do to help the gauge issue get resolved is to get their gauges to me so I can give them to SVT. If you'd rather, I can get an address from SVT to have you send it direct to Allen Park, though if they come to me, I can just walk across the street to Jamal's house and physically put it in his hands to ensure he gets it. They have not received a suitable amount of gauges at this point (way too few to diagnose accurately). When we've tried to corral some in the past, we haven't had much success getting them.
So please, if you have a bad gauge, PM me and I will get with you to get the gauges into their hands.
Ford already has alot of detailed data on which gauges went bad, on what year car, and with how much mileage, because they collected that during three years worth of warranty period.
