IQR 800 Engagement

What should my engagement be at? I can't seem to get it above 4300 rpm. Is this correct? Seems to pull hard.
My setup:
800 Non Ves, mild Porting, CPI single, 21-45 gearing, 144 track
Primary: Almond/Red Spring 60 gram weights
Secondary: Black/Red Spring 68.44.46 Helix

I have tried other helix and it doesn't make a difference. I have tried other weights and it just added or subtracted from top RPM.

So I assume if my engagment is low, I need to change my primary spring. Any ideas?

that is not low I would not go any higher it's just harder on stuff. Mine engages at 4k and pulls just fine
