Your current mods are not compatible with a Cobb ots stage 2 tune. Map notes require a catted dp. It would also be good to know if your hks dp is the bellmouth or the one where the wastegate is blocked (similar to stock design). They make 2 versions. Also, if your car has a tune on it now the ap will save that tune as the stock map when you install it so, if you ever uninstall it you will be going back to whatever map is on it, now tuned or not. Just something to think about.
