Did you have any comparison vs. the 2.5 upper pulley? my guess is 10 or 11lbs?
I will also update the chart once finished with tuning, and I can do some more pulls from 2,500 to redline with the new set up... currently only doing street pulls in 3rd gear going up grades in order to keep the top speed low. I'll do a top of 4th pull soon when I can find the right road / time...
