Tune question
 

Thinking about getting 3:55's put in my car from the 3:31's. I have a bama tune on it right now and I know that it will need to be recalbrated once the gears are in. My question is when they recalibrate my ECU will it take it back to stock and if I load my tune will it go back to reading as if it had 3:31's?

Pretty sure that's a user adjustable setting you can modify without having to do anything else. Choose Modify Parameters when you plug in the XCAL and scroll until you see the gear change setting.

Thank you. Im gna check today.

You can go into your tuner at anytime and change the gear ratio without it messing it up or putting it back to stock.

you can change it yourself on the tuner. i had issues with the revs per mile and had to play with it a little to get it right. not a big deal.

Messing with the revs/mile value on the tuner didn't work for me. I had to get Kevin @ JPC to just put the value in my tune.

I was never able to get mine to read correctly.

iv heard of people having to do this. guess i was just lucky.
