I can relate to your experience in S/P
I don't thank I made it pass the 1st round all year, I did get it to run 8.86 twice at 148.+ MPH on one run and then changed the shift RPM from 7000 RPM to 7300 RPM and it ran 8.86 at 150.+ MPH with no other changes one hour later at Woodburn, OR I love racing with E85 pump gas
I did find some things to fix and change this winter though, looking forward to going faster and quicker next year
