If i had an ecutek reflash with aftermarket bov and cold air intake, do i need a reflash if i went back to stock bov and a short air intake?

 

Which intake?The BOV doesn't matter as you cannot really tune for it.

 

I had a aem cai and shortened it to a shart intake.

 

Pretty good chance they had to tune for the intake and if you altered the intake after they tuned for it as a CAI your probably not getting a correct MAF signal now.Hard to tell without seeing a datalog.I would call who ever tuned you and see what they have to say.
