Just thought it was worth pointing out. My daily driver is an 8.1 BBC in a 3500 dually with a remote mount garret gt55. I run 7 pound springs in the gate. It has over 560k miles on it. And using the link above, this is what I got.

16 degrees of total timing on boost and has never run on anything but California pee pee gas 91 octane. And I don’t consider this a high compression engine.
