I have a 2013 Charger with a Maggie 800 rwhp, 2017 Hellcat with a whipple 1100 rwhp and a 2015 Challenger with a whipple 950rwhp. All have the same issue, they run great make lots of power and out on the street do the following. Do a wot pull thru a few gears and after letting off to come to a stop the engine light may or may not blink for a missfire depending on how bad it is. The cars all run rough and take a bit to clear up, then its back to normal again. sometime a few minutes and other times a few miles and then its back to normal. I never have a problem like this with high horsepower procharged cars just high horsepower screw blowers.
