Good tune, AFR good and was not running lean. Understanding is the stock internals were set up for peak power at 6,0000 rpms and if shifting regularly close to red line plus with 9 lbs. of boost, heat would this cause a piston to crack? Only other alternative could be the tune had too much timing regardless of the AFR and not running lean.

Anyhow, ended up purchasing a 2014 A6, ample bolt ons.
Sure miss boost, hence looking into a GM certified pre-owned ZL1.
On your LS3 factory rev limit is 6600 and we only move those 200 over stock to 6800.

We are seeing a lot of supercharged cars with inadequate fuel pressure/systems so it could have leaned out even if you didn't see it on the gauge.

If it shattered a piston it detonated.
