1994 Z28 A4. I'm going to be swapping in a 3.42 rear soon (2.73's currently). I don't have access to a laptop and was just wondering what the best way to fix the speedo would be. The car is eventually going to be a full bolt-on and cam car at the very least, so it will have to be tuned at some point. What's my best option (like I said, no laptop).

Thanks!

well, if your going to be doing the other mods soon, then just wait until you get the tune for your mods...thats what i did. Granted it sucks that the speedo is off for a while, but in the end its worth it...lol

i agree if you are going to do other mods just wait on the tune. i had 2.73 and switched to 3.42 and my speedo was off by about 20 mph. oh yeah the miles rack up pretty quick on your odometer so dont wait to long.

I'm definitely putting the bolt-ons on the car, but it's gonna be a gradual build up. My LS1 is way faster, so I'm not in a hurry to make it lightening quick all at once. Im gonna enjoy it at each stage as I slowly progress with the build.
