6AT > 6MT from a roll

Another point to mention is the Protune runs 18 psi down low; at 5000 RPM (in the powerband, the car runs 17.5 psi tapering to 14), the JB4 uses a 3 psi taper from peak, so if it is actually running 16.5 psi, it's tapering to 13.5 or so, so the boost disparity isn't much.

Either way, nice run.
