Kinda strange but I guess maybe a bad batch of gas? We will see what the damage is but Bobby seems certain it's in the bottom end and not a head/VVEL related issue. Think I got the car back in April if I remember right.

Even with a "bad batch" of gas there should be high detonation maps integrated into the tune to save the motor. That's what a knock sensor is made to do, but you can manipulate these maps in UpRev to not pull enough timing and add enough fuel. I could see if you are tuned for 93 octane, but put 87 in by accident and just ran the piss out of the car it may screw up a rod bearing or wrist pin, but having knocking issues as soon as you got it back after being boosted and custom tuned?... Makes you wonder
