Who knows what other carnage has occurred inside the engine.
Whatever you do, keep that boost under 40 and preferably 30 and baby that thing untill you at least get the tune fixed.
If it was me, I would park it untill it's fixed.
Good luck.

^^^^^^^^^this^^^^^^never ever ever exceed 35 psi of boost!!!
It’s not a purpose built race motor, don’t run it like one...... it’s a stock motor so run it like one.
Manifold pressure is not to exceed 35 psi
Exhaust temps should not be able to go over 900* or allowed to.
Period!!!
Don’t use higher fuel pressure to gain torque or HP.
That a quick and short road to injector failure and holes in you pistons.
If you want more fuel to gain torque, horsepower or both requires different injectors and turbo to correctly achieve this.
A change in injector pulse and timing can add some torque and power but not much. Of course I’m speaking of high pressure common rail.

If your tune allows you to exceed these just don’t do it. Watch your gauges and keep your temps and pressure under max ranges.

I’m not going to bash you for getting a tune but I will bash you for not knowing your limits and operating at or below those limits.
