Thx for ur kind blessing. Its 275kw at wheel, and im not planning run 1.7 bar any way, I did this to prove the capability of zage gt2871 and mtq injectors, I don't mind to be the first one to try sth other than blouch and injector dynamics.

As far as im aware, knocking is the primary engine failure factor (catastrophic cylinder pressure). Fatigue is secondary. I did compression and leak down before ordering new turbo. I suggest u have a read on this:

Friend just sold his sti with 365whp on daily tuned by mao, showed 2psi cylinder pressure difference on stechnic compression test.

Retune is just like doing a fifth gear pull. If a tuner is cautious, he will do small adjustment at a time and back off when knocking is heard.
