As The car passes the ~22mph mark, I notice the needle dips from idle to like 4-500 rpm and the car sounds like it's going to stall. After a second of this it recovers to normal idle.
The car has not stalled nor has the car thrown a CEL. Started happening this weekend.
Have a FR-S 6MT #1250 ~550 mi. New to boxer engines and MT driving. Had the car for one week, two Shell fillups from 1/4 tank already. Will call scion in the morning.

My guess is one of 2 things is going to happen:
1 - Subaru/Toyota says this is normal
2 - There's eventuall a TSB with an ecu update to minimize the rpm dip
It could be normal, and just coincidence that a couple of people had issues with the CEL which may not be related at all to the rpm dip we experience. Remember, most of us have not had a stall or CEL.... Although we can take our cars to the dealership, unless there's a CEL or TSB they are going to probably say the rpm dip is normal (I bet).
