Just got 4.10s installed but got a ?

[white07]

When I re-tune my car for the 4.10s with my x-cal do I just need to change the rear axle ratio? or do I need to change the tire revs/mile? Im figuring that the tires revs/mile are for bigger or smaller tires but im just making sure.

Doug usually sets his tunes up to allow you to change tire size with the X-cal but I don’t think you can change the gears. You will have to get him to make you a new tune with the 4.10 gears.

I did a search on SCT and it appears to be just a 4.10 gear input needed. If you change tires to a differnt size then input the rev/mile. Do a check to finalize the question if you can. Most of our highways are labeled down to the tenth mile here.

I just got back. I went driving beside my sister at 65 and it seems like it is on. Im running 65 at around 2500rpms. Does that sound right?

Yep that is all. Your rpm:mph looks correct.

Me? Love them. No whine. Only thing is, since I am probably staying n/a, I wish I would have gone steeper to 4.30's. But that's just me.

You answered your own question. Tire Revs/Mile are just for a tire size change. If the only thing you changed was the gear then that is all you need to change in the X-Cal.

And you expected something more out of that joint?

from the mile or 2 I just drove it and not beating the shit out of it yeah i think I like them. No whine from what i could hear. My buddy who works at ford did them for me. It was his first time doing gears but he had someone giving him tips when needed.

I got the gears for free, my ex-gf bought me the gear install kit, and my buddy did it and told me not to worry about paying him. So I guess getting a $500 job done for free I LOVE them.

I also just got blackouts which are on there right now. I just got my clear corners in. I got my new bumper in the other day. Now im waiting for hood pins and in a few weeks ill either have ordered or received tinted windows, black bullits 18x9 and 18x10. And I will have the grill that puts your headlights beside each other.

Here is a pick as of now. You will see why the new bumper is needed.
