But other modifications were made. I would ask them why? Possibly a wrong statement in the email. Would sort of waste tune day.

Starting from ground up. Tune was shit from the get go. Hot starts al the time regardless if I run 93/mix/ full e85. Also when I did wide open throttles, it would break up bad up top (not belt slip since I got new belt, and adjusted tensioner)

Specifically asked for a flex tune via email, so no confusion on that part.
