1.5 bar on pump is not a problem. I do agree if your IC isn't a full bay high flow unit your charge temps would suffer not allowing one to run 1.5 or even 2 bar. Ive posted before no matter what car I've built I always shoot for 100 degrees or less on boost charge temps on a 95 degree ambient day. On my current cars setup as far as my charge temps I usually see 96-98 @ 1.5 and 100-102@ 2 bar on pump. Race fuel will give you more torque and help control detonation if you are over your efficiency range. But if you turbos are well matched and your IC is big and flows well you are able to run pump without problems. If your on a track or running the car really hard like a mile event, it is stupid not to run good fuel for a safety margin.
