Would you need to set them up with pulse/tune etc or a simply 2hour slip out stock and slip in TTM?
I've heard second-hand from a user on here that the car runs fine in closed loop without a tune. Obviously the ST's are are going to be fairly high right out of the gate, but maybe if you drive long enough for the LT's to set, the open loop AF might look pretty good.
The only adverse effects I would watch out for is washing out the rings. Give the car enough time to adjust and set the LT's before going open loop and you might be fine. If it's still pig rich in open loop, get a tune. Other than that, I don't see an issue.
