There could be some validity to the claim of it damaging the cats, when the car is open loop the car runs more rich. Therefore coating the cats with unburned fuel, to the extend and does it really hurt the cats since when they come to temp it probably burns off....who knows.

I for one kept the cold start... so when I take it to the dealer and they start the car when its cold it sounds OEM, other than the exhaust. In other words they hear it go through the cold start procedure. Having the cold start feature removed is a tell tale sign that software has been installed on the car.

Just my .02..

PS..love the way the car sounds with cold start...especially with no primaries and a good cat back.
