I'm running a JLT2/XCAL2/Bama setup and may need to take my car in for warranty work if i can't get my axle moan to stop. I have 4.10 gears, so when i reflash to stock, can i just adjust the axle ratio while keeping the stock tune loaded? I'd like to take it in with the stock airbox and stock tune, but have my speedo correct for my 4.10s.

Can my xcal do this? thanks

I couldn't. I needed a speedometer only tune that cost me $25 from MPT.

i know with my SCT3 you cant change any options when returning to stock

thanks for the info.

so i have tunes from both brenspeed and bama.....should i be able to contact one of them and get a "4.10 gear speedo only" tune? hopefully for free?

why does it matter if the speedo is correct if you only have to have it stock for the service? you should just use the RPM's as a guage of how fast your going.

just to save you some trouble

Assuming you're going back to stock for dealership service, it does not matter. Just let it be wrong.

+1, just leave it be until service is complete.
