So I have a 2013 charger rt. Just finished forging the bottom end and also installed a gen5 3.0 Whipple. The tuner has written 2 tunes but I keep getting the red bolt on the dash.and the car runs like crap. Also stalls out and can't restart. Any ideas from anyone that has seen this. I was told it's a map sensor not calibrated correctly causing all this headache. Any help would be great appreciated
