Nice you get a brand new engine!! But over all piggyback tunes are not good the ecu is seeing false information that's why it gives it more boost.
Now because you seem to have bad luck I'd just stay with the tune Because you keep the warranty but preferably a real ecu flash is optimal.
It's crazy the computer didn't act fast enough and pull timing I used to over boost all the time in my n54. Something else must have really happened fuel dumped or just went really lean.
