Not sure if this is a simple question but here we go.
When doing enhanced OS did hpt change how they do this?
The HPT instructions say use stock or existing file.
So the latter part "existing " file, does this mean you know longer need a stock unmodified file?
For shits i did a 3 bar enhancement on my current modified file. It has a 4l80e segment etc etc.
The only differences ive noticed were the obvious , boost enrichment and the larger VE table.
Everything else seemed fine.
Thanks
