so i know no one really goes into this like they do with the trailing edge for peak rpm. since upgrading the charger i had to take my 15/20 to a 15/22 and rpms are exactly at 8100 now where my problem is out of the hole it revs to 8250 or 8300 so hard on the limiter. so my question is what do you think i should add for pitch to the leading edge before having to change the trailing edge to keep in the proper rpm range vs modifying nozzle size. i know that there is a happy medium between them all. but just trying to get a baseline before my nozzle rings get here. also many have said dial it close with pitching then fine tune with rings.
