 If all you were doing was changing carriers (same gears) then no setting of backlash is necessary.

Actually, it is the pinion depth that does not need to be re-set in that situation.

			well remember theres a crush collar on the pinion, and thats a one time use. and I was going from 3.08's to 3.42's so it had different carriers, and it was my dd at the time so I had to get it done asap. stupid move on my part. what can I say i was 19 at the time, when I thought I knew my **** lol.

 I will be able to tune 98 and newer cars in the very near future. I have been meaning to get with Foff to get set up with HP tuners but I have been extremely busy lately. In the mean time I do have someone that I can reccomend you to.
