I’m trying to track down the ECU tune on my McLaren 720S and could use some help from the tuning world, even if you’re not a McLaren specialist.

The car has:

* Weistec blow-off valves
* Titanium straight-pipe, catless exhaust with “Option King” / “Options King” plaque
* Downpipes and other supporting mods for high HP
* Very aggressive mapping (full throttle bounces off 7k rpm before redline, blow-off valves rapid-fire)

Here’s what I know:

* Weistec has no record of my VIN in their system.
* Car lived in Miami its whole life except for one random 1-month registration in Spain before coming back.
* Previously owned by Tyreek Hill (not the first owner).
* Tune feels like it might only kick in full force in Sport mode or at 100% throttle.
* No dyno sheet or documentation came with the car.

What I’m looking for:

* Tips on identifying the tuner without pulling the ECU yet.
* Recommendations for a *safe*, slightly detuned remap to make it healthier for long-term reliability (thinking \~780–800 hp instead of current unknown peak).
* Any info on “Option King” exhausts — I can’t find a single thing online.

If anyone here knows tuners who can remotely read the file, confirm what’s on it, or reflash without needing a full dyno session, I’d appreciate the lead.

Thanks in advance!
