Just a quick google find. Pre-ignition. Wouldn't that put added strain on a rod/piston if it was running lean? I think everyone can agree the pics posted indicate it was running lean. How lean? Lean enough to over time cause damage. How could the engine be running lean?
From my understanding, the tune for this setup was changed after my engine failure. Why, if they felt confident in it from the start?
Begs me to want to share more about the other first run M3's equipped with this kit but I will stick to my car and my case.
