I wouldn't get hung up on dyno numbers especially peak numbers. Get some quarter passes in. The road hp was very flat on your dyno runs. I'd expect 10.60-10.70 in average air with decent traction.Yeah I could barely breathe so I'm guessing the car was a little choked as well. I'll stop by in the fall when it cools down and we'll go for 600rwhp......I need the Buick to have more power than my Charger lol.
