i can say that im on the same boat that thinking 26* WOT is excessive. i would back it down to around 20* WOT and run more boost, but that's just me.
which is 100% the plan but im maxing the injectors now and dont see the point in any upgrades till i rebuild the motor in december so for now im sticking with 28 although as soon as the injectors go in a smaller pulley will go on and that number will come down
