I had a misfire on cylinder 5, swapped the coil pack to 6 and the misfire followed. Replaced the coil pack on cylinder 6 and went for another test run.

Now I'm getting misfire cylinder 4 & 5, multiple misfire code, and fuel pump plausibility.

What gives? Time for new plugs?

BTW I'm running JB4 on map 3 with meth/water, DCI, exhaust

How many miles are on the plugs?

Could have more coil packs going out, switch them and see if they follow.

I have had it, when I replace one coil pack another went out immediately after.

I'm not really sure to be honest. I bought the car as a CPO with about 32,000 miles on it. Just hit 40,000 a few days ago. Is it safe to assume that the dealer replaced the plugs before certifying it?

You were right, swapped some more coil packs around and the misfires followed, went to the dealer and bought all new coil packs, now everything is back to normal.

99% certain they did not touch the plugs. You are definitely due.
