Yes definitely iced down. It doesn’t help I drove it to the track tho. Elevation is a bitch man. And the DA is even worse. Plus my trucks is super heavy. My next project will be weight reduction. I did not log but I felt timing being pulled up top. Tonight is the night for another try!Hmmmm.... did you ice it down? Man i would think with that much HP the MPH should be way higher.... just my thaughts...maybe it started pulling timing on the top end.... did you get an data logs?
Good luck on your ten quest either way!!!!
