F12X drivability issue

[sg916]

F12X with Macboost stage 2:

Ski bogs bad as if turbo is stuck for about 2 minutes then breaks loose and is normal. Cools back down, same thing.

No difference on 91 or 100+ octane.

Nitro method check of waste gate ok. Turbo spins freely. Fresh plugs, same issues.

Any suggestions?

Any siggestions? Fresh plugs, fresh oil, (nitro method).

The ski his program to not build boost until it reaches oil operating temperature but unless you have some type of temperature sensing problem, I'm not sure why it would be bogging down.

Look for signs of restriction and or hotspots in the coolant system also check the water temperature sensor and oil temperature sensor.

Procedure is in the service manual.

Take the macs boost module off and retry it
