I like the planning you have put into your Sonoma GT project.

Posting information about tuning the EBL P4 is a very challenging topic. Dynamic EFI clearly states "Do Not Post On Any Board" on all the software I've seen and used. Myself and other gearhead-efi.com members have, and will continue to honor Dynamic EFI's request on what is acceptable to post on a public forum.
