What plugs and gap. I raced a bike 2 days ago and after I slowed down the car was running like ****. Yesterday I pulled the plugs thinking I may have melted one or something. Here is what I found.
My guess is maybe an o2 sensor died and it fatten up on one side. I had TR6s gapped .035". I am running 12# with meth injection. I was guessing it should make around 700rwhp but after only trapping 131 at the track I am either wrong on my guess or something isn't right with the car. What do yall recommend.

Mine was doing the same thing recently - drivers bank was fine, pass. bank was fuel fouled like that - it was actually an issue with the o2 sensor wiring, so I had my tuner turn them off and now I run open loop all the time. Theres also a small chance you have an intake or exhaust leak on that side causing them to foul as well.
With that much hp, if you still have issues after you look into o2 possibilities, you might try the equivalent to a TR7 (TR7 isnt actually a number on the plug, but you can find the actual part number thru a search on here).
