Looking for some help making the proper adjustments to account for a rear gear swap. Just went from the factory 3.45 ratio to 4.10 ratio. Made the following changes but think some may not be necessary or having the desired effect. A couple issues I am seeing. First, the speedometer is still a bit off (reading 60 mph = 70 mph actual). The other issue is if I put the car in neutral and coast at highway speeds, the idle is bouncing between 1000 and 2200 rpms. Just back and forth until I either press the clutch in or put it back in gear. I found this issue as I was diagnosing some gear whine.
Any help is appreciated. Thanks.
