It was about 2/3rds throttle. I'd like it to be able to go into third at highway speeds. 4000rpms in 2nd gear at 60 isn't exactly good for cruising.
And I slowly worked my way up to 60, I didn't start getting on the gas more until 70. As soon as I hit it the secondaries opened up and about a second later it jumped up to about 80something and I felt it shift into third and it went down to about 3000rpms
