I went to our local drag strip this past sat. my hellcat didnt run what I was expected I noticed on the way to the strip just about any time I would get on it...there would be black smoke a little to heavy for me.My best run was [email protected] and that wouldnt have mattered but I also ran my pro chargered scat pack and it ran [email protected] both cars running the same fuel 93 octane with boostane.the scat pack running 7lbs. of boost but the hellcat was running 17lbs. of boost it should have been quicker.I think it's in the fueling but not sure.
