Boost overlays

Here are the boost overlays. The bottom curve is post outlets. Boost and rpm plotted and overlaid pre and post outlets from the user posted datazap logs. The lower boost curve is post outlets. You can see the boost is 1 psi less initially and 2psi less for the majority of the run. Even though running 2psi less boost made more gains everywhere, a lot more down low, good peak gain, and great gain in the top end and a lot more peak torque too, all with no tuning changes. If tune was optimized for outlets and boost setback where it was supposed to be as in the pre outlets run, gains would have been MUCH larger!
