7153 update ?

[Casper]

I just look at the revsion in my 7153 it is 8r2. Should I download the newest revsion. In the download there is 9r02,and 9r03. I would say the 9r03 is the newest. What are the benefits of the 9r03. Does it remove any of the features of the 8r2. Like shutting off the rear o2,tire size,shift firmness,etc. Thank you

Updating to the latest will remove any OBDII functions like rear O2 disable.
