80% sounds about right for your power level and injector size (and no fuel pump rewire)

the boost spiked and cut off at 4k then when we traced it down to why it spiked it was fine and he continued to do pulls. Drove the car off it felt good did 2 pulls parked it for an hour left my house went to do a pull started misfiring new plugs went in the next day and adjustment to the tune which lead to this

E83. 80% IDC on 1220cc is about right on E85. 93 would be less IDC

thats what I run, kind of confused why it would spike to 35 psi. Before being tuned did you perform boost leak test?

Sorry, but he's trying to protect himself when he saw that spark plug.

The 35psi spike probably hurt it.

I wonder if it even made it out the combustion chamber.
He probably over wrote the bad tune to hide his mistake on 14th. This shouldn't have happened.
It happens more often than you think. It usually causes damage on it's way out though. Also, the ground strap erosion pictured is not a piece breaking off, that is heat eroding/melting it away. So you're not getting one big piece that has to find its way out.

This shop should not be getting anymore of your business, OP. Something is not right here.

sorry totally missed the e83 listed in your first post, but 11.2 is even safer on e83/e85 as some will tune to 11.8- 12.0 no issues. Iím sure since your running e83 he has some timing in there.

did the tuner hook it up this way? If so he should man up cause he just costed you a engine apparently if that spike cause this destructive damage.

My guess is he used wastegate duty cycle table from a big turbo. The stock turbo spools so fast that it overshot to the moon before he adjusted the table to make it more sensitive.

So at this point, find another shop to build your engine. Inspect cylinder 2 exhaust ports in head and turbo volute and exhaust turbine for damage. Anything else?

The only thing I could do is pray that the head is fine but I won't know until the head is off the piston is no where to be found either in number 2. the turbo feels fine the turbine still spins freely with no shaft play
