Well the timing looks great. With this confirmed, this is standard scenario of a skipped tooth on the timing.

I'm content with the tuner's response. Thorough and professional.

I don't think the engine slipped a tooth. I think it slipped a whole cam.

I still have the standard cams so can swap them back in easily enough if there is no benefit of running the piper cams for FI.
Which cams were in the car when the rods bent?

Standard cams were in the car when it died. Along with a completely standard head.

The spare engine is in and running. All seems well. Touch wood*

Dan will be checking the map on the dyno next week just to be safe. I'll drive it there gently. Hopefully this will be it sorted.

It appears I may never know what happened to the other engine.

You should knock on wood, not touch it

There are theories........But yeah, at this point its near impossible to figure out 100%

You are in good hands.

You might consider leaving the launch control off just for long term fun moving forward.

How lazy do you have to be to only draw one eye on your "art" and then copy and past it so your creation isn't a Cyclops?

Maybe he wanted 2 same looking eyes instead of a crooked eye beast?

Don't feel like it over revved once. If anything it barely saw the limiter once turbo'd

I think the assumption is that you over reved it when it was NA and you stretched the rods which weakened them. Once you turbo'ed it the extra torque and abise from launch control finished the job.

Ah I see. Well I can't remember ever getting a shift wrong but it did get drifted on the limiter an awful lot so could have been that
