Since my tuner switched me over to tephra, my idle is rough(sometimes cuts off), also now stays lean during boost instead of normal. Car cant idle with ac on either.

 

Sounds like you need to talk to your tuner, if they messed something up they should be able to fix it

 

That is not a Tephra issue, that is the tune itself unless something has changed with the car.

 

Sounds to me like they forgot to copy some of the tables over. Or you could have a vacuum leak that has developed aand causing your problems as well.

 

There are a few tables that can be tweaked to adjust all of that... Talk to your tuner

 

Definitely talk to your tuner.. My car did the same thing when i first got a dual map tune.. It just didnt feel right so after taking it to him a few times and having the same problems i finally decided to take it to a different tuner and it resolved alot of my problems.
