    Does anyone know HOW the black key lowers the horsepower? What changes are made with the engine to slow it down??

    drops to 500. Boost and timing I would think have not looked into it. But when I tune cars that's the big HP gain

    I actually thought it would be cool (if I do let someone else drive it) to use the black key but not tell them until after. THEN pull out the red key.

    Can anybody feel the difference between the red and black keys?
    I know that 200+ hp difference is a lot, but I would like to hear from somebody with a Hellcat, not a magazine

    Can you lower to 500 if you only have the red key with you? B

    ;)I've been using the black key up here in the northeast for winter driving to hopefully minimize wheel spin and going sideways if I happen to get on it a bit too hard. It's a noticeable difference, but still has plenty of power.

    I would use the red key and just activate valet mode and then turn on dash cam

    LOL, too funny! I took my best friend for a spin last weekend and scared the crap out of him, and said that's just the black key, he said Huh? So I had to explain that was only 500hp, he said You're kidding me, right?:p
