Yes, you'll find a bunch of threads if you search this forum. I use a mechanical Roush gauge on my '13 XLT in a Roush pod: http://www.ebay.com/itm/like/400627215649
I've had it almost two years. I like it overall, but it tends to stick when I have the heat blowing. It seems to favor cool air. Also, it will be too bright at night. A "PWM" dimmer with switch will make it much nicer for your eyes for night driving.
My stock eco motor runs about 13.5 lb under max boost, like pulling a trailer uphill.
