I also forgot to mention to clean out your intake manifold of the oil puddle that is probably in there. The oil will drip into your cylinder and cause spark knock. The catch can recommended will resolve any further oil from getting sucked into the intake manifold.

Thank you so much....

In general, you want to get your knock to as close to zero as possible. As mentioned before, each car has its own needs and therefore, do some datalogging with the predator and fine tuning of the fuel and timing can be used to maximize the full throttle performance. All of this stuff should be done AFTER you have cleaned up the intake manifold and fixed the oil issues with a catch can. The oil will cause knock so if you try tweaking the predator tunes before cleaning up the oil and such, then you will be chasing your tail.
