Something I've always found helpful for sorting out the rev ranges, is to calculate the speed that the car is doing on track. IMO, trying to figure out the lowest RPM that the motor turns on track, and then setting the start RPM to suit is best. From testing with a data-logger, usually the lowest speed (regardless of class, as we're talking corner apex speed) is around 7-9mph. So setting the start RPM by back calculating from the roll out and FDR. It's easier than it sounds, especially with this excel sheet.

Again, from your settings originally posted, along with higher start, maybe also try less boost/more turbo, and also a higher end RPM. Also, don't forget, you don't need to use all the dynamic timing, if the track doesn't allow it. I've seen plenty of situations where adding more timing hasn't made the car any faster, and just added heat.
