Well folks no better way to put this, but say it, the stock block has it's limits even in the 2011 model, it's right around 400whp as mine fired a code for number 2 misfire pretty much the same day the tune happened, compression showed that number 2 had only 75psi and 1,3,4 had 150psi
Next step is to make appropriate changes, car is back in the shop (they are working with me as much as they can to help me get the car back on track) and a decision will be made in the next few days as what route will be taken to guarantee 500whp with out any more issues!
I will post pictures of damage as the motor will be pulled and built as it needs to be.
Will keep you guys posted.
Most important lesson here is that don't push the stock block past 22psi, I would even say 21psi unless you built it, unless you will accept the fact that it will go boom very soon in my case a worst case scenario pretty much the same day it was tuned. OUCH!
