I'd say give the plugs a shot and see if that solves your issue. Swap the coil pack between cylinder 3 and another cylinder that never gave a code while you're at it. If you still consistently have a misfire code like that, I'd take it to ENZO and see what they say.
I would try aftermarket plugs since you're tuned. These are what I use per Terry's suggestion, gapped at 0.022in
