I was wondering if anyone has had success installing aftermarket gauges into the stock cluster and what specific gauges would you recommend? The Revolution 3 3/8" GPS 180mph Speedometer and the 4" 8k Tachometer look very interesting and do not appear far from stock.. Also, if the tach and speedo have been replaced, how did you take care of the inevitable "check engine light" that detects the missing speedo? The odometer might be a problem with other gauges but not a problem with the Revolution gauges, since the GPS Speedometer has its own built in. Thanks for any help.

 

Lots of good info here:
