Brake boosting is: modulating the throttle and the brake simultaneously, in an effort to build some boost. When you let off the brake, you are already accelerating under (some) boost. VERY effective in roll racing.
...thanks.

Not sure my shift times seemed a little off on the graphs. Normally I'm a bit quicker but its hard to say. All depends on how well Todd can drive a stick. That is with me on pump and him on race. Race vs. race would be a different story i suspect.
Ben looks like you shifted well. Looks to me like the pump gas tune is pretty mild. Hopefully you can get some race gas this week and try it out prior to the mile.
Do you have a separate program for race gas or does ECU adapt?

I feel that brake boosting levels the playing field when compared to NA cars..

How does brake boosting help 60-130? My understanding is that the car gets a running start (say at 35 or 40) and blasts through 60 at full boost wode open on the way to and past 130.

Based purely on the graphs posted, you can tell that the only reason Todd caught up was b/c of Ben's "relatively" (especially as compared to an auto) slow shift. When in gear, the pull seems to be virtually identical. Congrats Ben!

You may or may not be at full boost by 60mph if you just stomp on it. When you break boost WHILE you are at 35 or 40, you get to full boost sooner...
