Installed the performance tune and it works great...Now the only bad thing is the gauges and monitoring,I add all my gauges and when I go to monitor the gauges come up and just display random fluctuating numbers on all gauges,how can i fix this problem so they monitor properly?

random, fluctuating numbers?

FWIW, thats what I usually expect to see....can you be more specific?

Let's just say for instance the RPM gauge reads 0.00,250,750 over and over again never reading proper no mater what rpm...temp gauges,MPH gauge all the same. I understand the numbers are supposed to fluctuate but if I'm doing 1500 rpm I'd like my gauge to tell me that.
