We rec. starting on Map 1

I see you are misfiring- commonly happens especially once adding any tune (JB4, flash etc)- a more agressive tune puts more stress on wear and tear ignition parts- any idea how many miles you have on your spark plugs or coil packs? Might be time to replace.

Once you get your misfires sorted- throw up a log and we can check things out!
