I run the boat anywhere from 174 ft elevation on the colorado river to 2000 ft elevation. I understand the elevation and air differences between hot and cold. I appreciate all of your input and will continue to post testing and results. I am pulling my injectors and having them gone through this week. Just a clean and testing. I am also picking up a 25P fury from one of my buddies to run and test. I will post results. Thank you all for helping me on my quest for 80MPH
