OK I played in an SRT yesterday while the deck lights were getting replaced with the myGIG update. This is what I found. The inside buttons activate the same stuff that the RT has been doing.
0-60
MPH (still have no clue what records top speed)
Blank meter
RPM/MPH/temps/battery
Compass Raw measurements 0d-359d Outside temp ave/raw
MinLMinRLtRt19gavg? (What in the heck) alignments?
Software (exactly the same SRTvsRT)

As far as same info that is in the ###Performance### page in the SRT - (Lets finger this out as to how to activae it in out RTs)

My service tech was a bit mesmerized by what I was showing him, he said it couldn't be the same in the SRT, then was mesmerized again when I showed him.

One of the techs was trained by dodge on the Challengers and Chargers. It may be the same but the computer has settings that the RT can't get to (unless we figure out how)
