I hear u about fine tuning first. When we are the engine dyno, all I wanted was 1000 hp and that's it. First pull was 1080 at 5200 rpm with 20 plus boost with a 13.4 AFR as my wastegate wasn't bleeding enough boost. I also learned a lot of screwing around with the Blow thru carb based on my dyno experience with the help of my Good Friend Charlie!!! I wanted to turn up the boost on the last pull but I had some header leaks and didn't adjust the home made boost controller to make a difference in boost. I wanted to run 20 psi to see how much power it would have made but it still went to 15 psi on the last pull. My motor was on the dyno for almost a month with 50 plus pulls due to fuel pump issues and waste gate issues.
