I installed the JB4 yesterday and kept on map0 until I got the plugs put in. I gapped them to .022 and installed today. I started up the car in map 1 and I have a check engine light. Car sounds a little rough too.
Did I just mess up the spark plug install or is there anything else I should check.

23 stinger GT2, ark down pipes, Velossa tech snorkels, JB4 (have EWG wires, not hooked up yet), HKS plugs
 
Read the check engine code. Can't tell you much without that info.
