Yes you have the NPP code dual mode exhaust and you can get a controller from Forza to be able to switch it off and on. You say your having a issue with delayed response from the car while in neutral with the clutch in giving it gas and that is weird as I would think the sensors could be off, the TPS or something..... I would look over the connections to the accelerator pedal. And maybe it is wanting to stay in the same rev band to shift, and maybe like many you naturally let off when going to shift to try to rev match. I know I don't step on it harder when going shift in that split second.....LOL

Anyway congrats on the new ride!, is it used and maybe had a throttle controller installed on it?
