I am running 87 in the winter because 40 cent diff and I am in Upstate NY so snow. No need for more power. Once time hits for my Summer Tires it is back to 93.

If i wasnt running a tune i'd probably be running 87. I felt no performance loss when stock, and the ecu will make timing adjustments to resolve any possible ping

My Boost gauge only hits about 16psi with 87. May be cold temps and keeping boost lower to stay within the torque range. If the computer adjusts for that.
