Likewise if engine load is lower before the turbo is making maximum boost, adding timing can help increase torque to make up for the lack of boost.
For the AFRs I understand since my AFR gauge is mounted after my mid mount. The tuners generally tune accurately off the factory widebands on the vehicle rather than the after market gauge. It builds quickly but holds 14 psi the entire way.

I had a instance where I was placed at 11 degrees of timing and maxed out at 14 degrees by redline but a different tuner. Which would probably be safer snd conservative I assume?
