Any Turbo experts in here?

Helping a friend with his car right now, it's a 2015 with a twin turbo Hellion system. Has a fore fuel system to run E85. We have a Lund tune and we are having a weird issue. The data logs are showing fuel trim ,spark all ok. Also we aren't getting any knock at all. We have proper plugs and gap set. At higher then 5500 rpm we are getting a random misfire check engine light and it's breaking up bad.

We checked compression in all cylinders this morning and it was between 200-215 on all cylinders. Trying to figure out what could be causing this issue?

Could it be a Crank sprocket going bad? It still has stock OPG and Crank Sprocket.

Thanks

I've been known to dabble....I read turbo for dummies once, so you could call me a professional. Unfortunately I didn't bring my book to work today so I will be unable to help.

You can try crank relearn for the misfires.

What's Lund say about the logs?

 

[Azmike]

Lund said all is good on the logs!

Check coil packs? There have been some failures.

What are the plugs gapped at

Check the plugs and swap out coils. I had this issue and it was coils as per Collin at RI
