Accuracy??????????????
 

How accurate is the gear analyzer on this site? I'm going from 4.10's to 4.56's and shifting at 6800-7000 rpm, says ill be shifiting at approx. 36 mph for 1 st, I entered 4.56 as desired gear and 28" diameter tire. If thats true, then my 26" summmits and 4.10's must be spinning like wild. I currently shift at about 20 mph in 1st. car is sputtering in rev limiter 7200 rpm.
The shop installing my gears is worried about my roll out.


BTW: NICE BATTLE BOXES *******RICK91GT:D
