True, I would say best bet is to just take it to the dealer. Might as well have the pdim updated if you havent done that yet.

That being said, I dont think theres a tsb about the ecm issuses with l99s yet. So seeing how GM is a dont fix it if it aint broke company, I would guess they wont update yours unless you complain about it first.
