Once I get some logs with the 17.4 spring sent to Brad I'll see if he minds posting them here, I added the barometric PID to my data log file a little while ago because I thought it would be nice to see ambient pressure when logging.
He sent me the modified tune, we are also trying to shut off the Electronic BOVs, so I can fully remove them from the car, so a little testing will be needed. If that works, I will be super happy, but worst case I will go back to how others have done it, and cap them off and zip tie them out of the way.
I seem to have gotten lucky in my travels as the E85 stations nearing my parents house are few and far between, but close enough to get me from one to the next!
