There is no such thing as a one size fits all gap, so I hate the idea of just following an arbitrary size, you must do what works best for your car.
I'm trying to run stage 2 91 tune with pump gas consistantly. FBO, no E85 until I decide to upgrade HPFP in the future.

What gap do you think is relative best for me? 0.028''?
