Y'all metric guys need to start listing 60-130 for us Muricans. Plus, it's a more widely used gauge. :p

nice thing about 100-200, auto and manual guys are the same, only need 1 shift

60-130 usually requires 1 more shift for auto guys unless they changed gears or ran taller tires. so there is less variables in the 62-124(100-200) run and makes it easier to compare.

Curious how you arrived at the 13-15psi target for the track use?
I broke in the turbos at that boost pressure and it was very controllable and easy to handle. Sure I can hot-lap full boost but i’d be going basically twice as fast and i’m more worried about my driver skill. Also most of the tracks around me aren’t that fast
