Gear Swap (no tune yet)

**tatertot91** · 01-16-2010, 06:42 AM

So my rear end is in bad shape and its getting a freshen up
Has 2.73s and an auburn and i'm going to a 3.55 and a torsen (till i can afford a 12 bolt)
Only thing is its probably not gonna get a tune for the next few days, no longer than a week. I know the shift points will be off but will it be bad enough to where i can't live with it for a few days?

you'll be just fine. The biggest problem you'll have is the speedo will be off by a bunch. It'll shift just fine without a tune.

I have wondered about 3.55's let us know what the 2nd to 3rd pull is like and where #3 tops out out. 3rd gear is a huge dead spot until at least 100 with 3.23's.

All a tune is going to do for that swap is correct the speedo as stated above. You'll be fine.

I'll let you know soon as i know
Should be installed next week
Was planning on 3.73s, but my installer had 3.55s laying around and i figured it would be a good balance for when i hit the highway
