It appears the latest firmware is ISTA/P;2.48.0;E89X-12-11-507, just want to confirm.
Beware of Sterling. Not the brightest of techs. Just had a customer's car there and they were very unsatisfied and will not be using them again. I suggest contacting Marco at McKenna Performance if you want a dealer to do it.
