I talked to Delta a few months ago but decided not to spend money on cams right now. They had three options available at that time. I believe 264*, 272*, and 288*. Its been a while so you will have to double check. Either way, Im pretty sure you have more than two options. A few people around here have had delta regrind cams for their cars if you look around.
The ECU cant really even compensate for the mild cams. If you want to go to a more serious cam route you should really look into a standalone management system in my opinion.
