How do you know 100% it wasn't knocking? Just from looking at the AEM? You can't soley go off that especially if you didn't put race gas in it and calibrate the noise tables in the AEM. Or did you put race gas in it and run low low timing and low low boost to make sure it was not knocking and then zero out the noise tables in the AEM? Or is the 3S totally different when it comes to monitoring knock? How is their knock sensors compared to a 2G DSM?

Running pump gas first thing is a big gamble in my opinion. Especially on a pretty radical car boosted like you were building. The pump gas numbers are awesome but I have a feeling it was detonating and killed the rod bearing in #3. The proof is in the pudding though when you pull it apart.
