Got my normal E10 gas in the car and did q datalog after 70 miles. The car had 2 gallons left of the E0. I will have to make a spreadsheet with all the data when I am done but I am glad I did not sale my plenum spacer.
Engine is still pulling 9 degrees of timing at 3000 RPM's without the plenum spacer. Same tune with the plenum spacer had 0 degrees of timing pulled. Discuss.....
