Regardless of whether I used BP Ultimate or 98 from United, I have never had any issues with detonation with the higher boost.
Add in just 4-5L of e85 on a full tank of 98 and you will feel a noticeable difference in smoothness and refinement. The OTS 93 Tune are sometimes tuned a little too aggressive for our aussie fuels. I experienced the same on my F80 on a BM3 stage 1 93 OTS tune. Once I get my G80, I will be running jb4 on map 5 using e85/98 blend from United
