71 Duster 360 turbo build

Started a thread in the transmission area. I feel like I’m down on power and wondering if I’m blowing through the converter. Pretty sure I should buy a certain PTC converter for sale on here. Spoke with John cope and he said my logs look like I opened a parachute after shifting into 3rd.

This is essentially showing 2.85 seconds from 100-150mph if there was nothing slipping between the crank and tires. My car isn’t that fast.
