Yes your ground speed is down and your ability to lug is the biggest factor. When you put stiffer spring in it now takes more rpm to sling the wieghts out and advance the timming .

It also shows that when the rpms get higher requiring less initial advance timming the the torque runs flatter and higher. typical of needing less timing to pull on the top end of rpm range. hope this helps
