How to get to 550bhp?

I have a 64 plate M4 with the exhaust mods and pipercross filters.
I had it remapped and got 512bhp and 560lbft, however the bhp starts to drop at around 6k and I was wondering what further mods I would need to achieve 550bhp.
Exhaust mods are secondary cats removed and reworked back box.

Curious, how are you measuring bhp?

What tune are you running

On stock turbos power will always drop, but your graph is not as flat as typical stage 2 dynos I've seen

501whp is around 550bhp for my car

This was done here in the UK by a top tuner who owns a M3 and has spent 3 years developing the software for his to achieve maximum lbft torque.
This car is now epic on it's pull through the rpm's but I was just wondering if I could hold the power curve at top end with a hardware change.
