Interestingly, this is the first I've heard of it being applied actually in response(?) to a CEL.
Since then there's been one minor uptune and since then can't say I've noticed more changes, but 3rd gear doesn't get the boost/torque it should; 12PSI rather than 15-16, and that's disappointing and makes me want to retune because there's an obvious responsiveness defecit in 3rd. Cetainly far tamer than delivery.
I believe they may in some circumstances adjust the flash in ad-hoc ways, so that the software on one may not be exactly the same as others.
