i had a friend put a rpm gage that had a programable shift light built into it . he got it from autozone and just mounted it on his dash and wired it to the stock rpm gage
the upshift indicator in my car is retarded.Even though my rev limit has been moved up to 7000rpm,the up shift light still comes on at 6000rpm.It still works will cruising though for gas mileage purposes so thats nice .Contact vince @ trifecta and see if he is able to make the BCM turn the light on the cluster
