i will be going back to the dyno this monday hopefully ,my dad is taking his stang.ill put it back on for 2-3 more runs with boost and a/f.while the car was on the dyno we did both increasing timing and removing fuel,and it make like 1 more hp.

Pull like 3 degrees for one run in boost. Just for shits and giggles.

Lulz. Nah no blowing. But I'm thinking power will stay the same or go up. Seems aggressive to me. Fwiw

If he retards timing 3 degrees his afr should go richer, so unless this gets leaned back out to the previous afr as well, probably not going to get the data your looking for. I can tell you that max timing right before detonation is going to yield the most power though. Retarding timing and removing fuel can sometimes add trq/response, but its at a sacrifice of the latter. On a SC car the trick is to blend max trq at a lower rpm where it suffers wile making less boost, then add fuel and as much timing as you can as you get into the powerband of the motor. The nice thing about sc is its totally predictable and repeatable every time so building a timing and fuel curve is a snap and you can be more aggressive in one area of the curve vs another.
