I drive a automatic 2013 Camaro 1SS. Last May I was able to have GPI install their SS1 VVT cam. One big reason I went with this cam was on their page it was sold as it works well with the factory stall converter. Which it has I've only put roughly 4k miles on the car since the install and no problems no complaints at all. It will buck or surge some at lower rpms cruising through my town at 20 mph coming to a stop. But that seems to have gotten a lot better or maybe I've just gotten used to it. Today one of the techs at the local Chevy dealership told me I should have a converter installed that's the reason for the bucking and will burn my transmission up. Not to discredit either side I would just like to think I could trust GPI more than this small town Chevy tech. is this something i should have done to my car? Or even if my car doesn't "need" it is it something that could improve performance and or health of my car if I had it done?
