I just got in and installed some indiglo gauges in my GT.. my question is the MPH goes up to 160?!... but i'm not sure if the needles stayed calibrated or not.. i think they did but I think the numbers on the gauges are off.. i seem to idle around 1200 now instead of the like 900-1000 i was before.. and the speedo reads about 80 when it doesn't feel like i'm doing more than 70... any suggestions
You got the wrong gauges installed...
This is the difference between the GT and GTS Gauges
GT Speedo is numbered to 140mph
GT Tach is numbered to 8,000rpm
GTS Speedo is numbered to 160mph
GTS Tach is numbered to 9,000rpm
