E85 tune completed at JM Auto. The car made 608WHP and 583WTQ at 38psi on their dyno. It is known to be low reading, so the "Shootout Mode" numbers are used as a reference to the local Dynojet. The numbers aren't too important to me as long as the trap speeds are there. Overall the power seems to be holding great and is about where I would expect based on the boost and fuel.
