I think FoMoCoSHO ran as high as E45 at one time with an AJP tune on his 2015, which was stock otherwise. Lot of lessons learned along the way. So E30 should be very doable on 2013+ with the stronger OEM HPFP. Bit more of a challenge on the 2010-12 with about 500 psi less headroom, but still doable.
