it's in neutral and it has the lower rev limiter?? If that's the case then that's normal. See if it's in neutral, then there's "no load" on the motor. it's a Safty feature so the motor doesn't free spin and casue damage.
It might be limited to prevent folks from blasting the clutch & tranny with 8k launches. I've read every review I could find and nobody mentioned this so I call it "unconfirmed" until a few more people verify it.
I'm telling you it's a No Load limiter. You're right it to prevent tools from blowing their motors. But not from hole shots. Get in Any V6 Accord and try Redlineing it in N or P. Honda has been doing it for a while now. That limiter is actually similer to a Performance limiter found in the MSD Digital 6+ box. Where it shuts off alternating cylinders.
