Well now that you have made the sprocket for the exhaust, you will have more gains and before 6000RPM. At Least thats what i expect to see. but one thing that you might have is an increase in low RPM torque and quicker spool up.
While tuning an EVO10 that has both cams adjustable, we set advance on the intake and retard on the exhaust, and we ended up with what i mentioned above.
