Interesting Doctor visit

Went to my monthly Doctor visit the other day and met a guy with a 2017 392 ScatPack Charger, Told me it had 550 horse power and a top speed of 250 mph!!!! Now I'll be the first to admit that I do not know anything about the newer cars so I just listened to what he had to say and left for the ride back home, well who pulls up next to me at the red light, He asks if I want to go I say sure but don't want to here any crap about traction control or something else being wrong if I win, OK I left with three car lengths on him and he could not catch me, I lifted at 120 and he flew by me, he pulled Ito a gas station and I followed, He said he forgot to take it out of 4 cylinder mode???? Now if that is true wouldn't it switch to 8 cylinder when floored, take the damn loss and don't whine. I've done a lot to my car, 1970 340 Dart and told him I'm probably close to 400 H.P. what do you'all think. 4 cylinder mode????
