My E55 has been having very slow acceleration than what it used to. It feels like the car is 200hp. I don’t know if it can be heatsoak because the problem is there as soon as I start up the car and never goes away. I have no codes popping up anyone know what can be wrong?

Intercooler pump is bad more than likely

I was thinking that too but even when I first start the car and the supercharger is cold power loss is still there. Supercharger hasnt even had time to heat up yet and power loss is still there.

Maybe the clutch isn’t engaging the supercharger.

If your intercooler pump is failing or failed, your clutch won't engage the blower at all and you'll be at an almost complete power loss as this is normal with a bad IC pump. It is irrelevant if the blower is cold - it won't make boost/heat without the clutch engaging. Are you modified?

Bosch 010 is tried and proven - there are some other more advanced products that have come out over the years, but my Bosch has been going strong and no reason to swap to a newer version/product.
