Loss of compression in two adjoining cylinders often points to a communication between the two, such as a cracked head, cracked cylinder, etc. I suppose it's possible that ****************ty fuel caused donation and wrecked something..

I think I’m going to have to send it to porsche. if it does turn out to be fuel i’ll want to go the dealership route. it’s a real bummer, i was planning a road trip june 18th and was completely redoing the suspension before hand. Fingers crossed there is bad gas.... i can’t afford anything else

Just because I am curious.
You stated that your running headers.
Do you have other modifications to the car???

You could pull a fuel sample and send it out for analysis.
I don't have a clue where you would send it.

I’m having the car towed to the dealer. the service guy said having two cylinders go out like that is strange, but of course they want to get paid also. fingers crossed for bad gas at this point

Keep us informed if you would.
I always like to know outcomes and causes.
