BMW 530D LCI E60
Hello.
I have a e60 lci 530d. Tuned somewhere about 300hp/650Nm

When i start to accelerate from 0. it is very slowly gaining rpms. And when it hits 2500rpms it almost snaps my neck

Now i am stuck with power loss at low rpms.
P3263 unknown trouble code.

I have checked boost leaks. There were none.
And the turbo works too. Bearing is good as new

I have changed
Maf, lambda and exhaust gas temperature sensor.
Nothing works.

I hope you people can help me.
Sincerely Mikko
