Im wondering if anyone has worked out a way to run a lower static fuel pressure in higher boost ranges in order to keep the fuel pump happier? Something similar to a wastegate that opens at a set boost to keep fuel pressure steady as boost continues to increase. If you have a lot of headroom with your injectors you might as well since the extra pressure isn't needed. I don't think this would effect the tuning process as any tuner is going to be going over the WOT settings with a fine tooth comb anyways, so you won't have to do any extra tuning/changes really. Im just trying to think of a way to avoid those almost triple digit fuel pressure readings one would see running a stock fuel pressure and a worthwile boost on turbos of these sizes.
It would probably be much easier to simply drop base fuel pressure to mid to low 30's as cars like these won't see much street driving anyways, if street drivability would even be drastically effected.
