I strongly suspect there is a significant percentage of "End User" or "Project Owner" types favoring and purchasing the "Self Tuning" aftermarket EFI system vs. "Tuning" a factory EFI System.

A few thoughts I have about OBD2 tuning software:
What OBD2 tuning software suppliers offer "Demo" versions?
What OBD2 tuning software suppliers maintain a website with "Stock Calibration" files that are available for download?
What OBD2 tuning software suppliers "sell" the most recent "Stock Calibration" file for "Your VIN"?

Personally, I'm sometimes a touch nervous about using OBD1 or OBD2 files I find on the internet. The OVERWHELMING majority of OBD1 and OBD2 files I find on the internet are valid!

I would favor a HPT section with the following guidelines:
We have a dedicated HPT Moderator, who owns HPT and has intermediate to advanced skills with HPT. (I do not own HPT)
HPT offers a "Demo" software.
"Stock" files only.

HPT maintains their own tune repository. That said theres a mix of stock and edited tunes...

There is also someone who maintains EFI Live stock tune files on a file sharing site called "dropbox". So farbive only found valid stock tunes...
