A piston manufacturer doesn’t matter as much or forged or hypers, if the ring gaps butted together. Butting them up on boost is a common issue around the forums.
I’m glad you run water/meth, what ratio?
In my opinion, your timing was way too high at 27. That’s less than 1 degree of timing per psi of map. If you experienced detonation, you may have damaged it then. Detonation is a wild animal under boost.
