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
