Hmm good point.
But admitably a clogged cat. converter also feels a bit sluggish or it gets hard passing a certain speed.
Albeit, I only experienced this once in a stickshift.

Good to know, it feels way better now.
Non the less, check what we recommended and see if the shiftpoints are correct.
May you clarify what and how he checked and deemed the trans to be ok?
