Good news! Softronic offers a tune for the 3.8 five chain overbore, just under $1,000 including cable.

With their reputation combined with the reasonable price this will be my choice for a flash. I am now pretty convinced that is safe to run the 3.8 with the stock DME, But more power is always better if you can swing it!

Thinking I will get the car running with the 3.8 with the stock DME and then do the flash later. Not 100% sure, but plan to do at least one dyno run. Probably after the flash, but one before and one after would be interesting too. I have asked Softronic if they think a dyno run with stock software is safe from over lean condition, will report what they say.
