I would pay an hours labor to have that done, but I haven’t spoken to the dealer and my gut tells me they’d say no way you have to keep your car stock and I’d say it is stock for a GTA, but I don’t know, I really want that done as well as the transmission tune because of everything I’ve read about them both but I would bet a fair chunk of change. My dealer would say no maybe I should try the other one in town.
