Always wanted one, so found what I thought was a decent car at a decent price. 2010 GT500 - one owner. Spotless. Navigation System Shaker audio w/1 CD instead of the 6 it was advertised as having - not happy about that . . . Prior owner swapped out the tail light with an alternate set, but left the original ones in the trunk. Brembo brake system Kona Blue 14,000 miles Not the original tires which I didn't like until I saw the original owner put 20" Foose wheels all around and tires that were rated as high as the originals - 168 MPH. The Foose are $320 a piece and the tires are $300 a pop - NITTO INVO Ultra-High Performance Tires $36,000 The rub is the gauges styled like this: I want them to read what they are while I drive. By odd trying the oil one reads right. The others water temp and boost I played with endlessly with no luck. I'm confident they work. Each gauge has 2 rubber covered buttons. One on the left (Marked "W") pegs the gauge, turns red when pushed as it maxes out. The button on the right (marked "P") used to read, then return to 0. I looked at the manual, on line with no luck. I has to be to sequence of some sort. All I want is for the gauges to read properly when I drive the car. Any help is greatly appreciated.
