Buying this for a 2.7t would be pointless and actually counter productive, unless you just like the sound. 2.7t use diverter valves that divert unneeded pressure back into the system filling pressure back up quicker for next shift.

I believe that’s the process, could be wrong, but I know that the 2.7t doesn’t come with a bov.
