Default Heavy misfiring in boost after AVCS Delete.

Just got done doing an AVCS delete on the car and am now having a bad misfire only under boost. The car has the exact same map on it before the AVCS Delete.

The car drives awesome when cruising, idling, etc. At around 10psi, when the boost starts ramping up fast, is when it starts happening. It almost seems like its a dead hole when it hits boost. It feels like it hits a brick wall/big choke when the boost comes in. It achieves full boost and the wastegate opens just fine.

I have logged the car and I haven't seen anything out of the ordinary when its doing it. I even logged misfire counts and nothing popped up under WOT. I have NEVER had this problem with the car ever. This is definitely a first for this car.

I do have a few questions when it comes to the AVCS Delete:

I do keep the AVCS Solenoids unplugged and just delete the codes right?
Do I need to zero out the AVCS tables?

And here is a log if anyone would like to take a peak. The log was done in 1st gear:

Did you swap to non avcs cam gears/bolts or just unplugged your avcs solenoids? Either way your tune will need touched up because your intake cam timing will not be actively changing anymore.

Nevermind! For some reason a plug crapped out on me and all is well now!
