Just wanted to close the loop on this thread. I was able to get on the dyno after installing the EWG and converting to E85.

The initial tune was done on the road on pump gas, then I swapped fuels, tuned the boost, then booked time to tune the timing on the dyno. I'm really happy with the results, and couldn't have done it with out the HP Academy courses.

P.S. I had a MAC 3 port disassemble itself after my first pull. Fired out it's internal piston. Took us a while to figure out why the car all of sudden wouldn't boost over wastegate pressure. Threw on a new one and was able to complete the tune.

Dyno sheet is attached. First run is pump timing, second is with timing optimized for e85.
