I have a customer here with a 2011 wanting tuning. I checked the supported vehicle list and i see its still only to 2010. I know they changed the pcm which is making it take longer. But I'd like to have a straight simple answer for my customer. Is it being worked on?

My understanding is no. New pcm is supposedly unreadable and hpt standpoint is they will not support something that they cannot read and write too.
Both EFI and HPT have said they will not be able to support that PCM. Handheld tuners like bullydog and H&S are the only option at this time.
