BMW 740d F01 2010 - No power

Hi there, I hope I created a topic in right section.

What happened, my smaller turbo started playing and it died, smashing all cartridge inside. Garage changed turbo, BUT forgot to clear intercooler. Started car, tried to drive it, and it turned up for AUTO-RUN itself for 10seconds. A lot of smoke was coming out. Then garage cleaned intercooler and pipes, all was cleared. Its 740d 2010 F01 model. We put reconditioned turbo with actuator. Before that, car was remaped, and it was pulling VERY GOOD (700+ torq), 370bhp. Now, i sit down in a car, and there is NO POWER. What could be wrong? Engine is not shaking or anything, drives like a normal but looks like Remap is gone. But how comes? No one touched ECU. Yesterday, tried removing AFM, cleaned it, but nothing happened. Turbo is working perfectly, giving exactly same boost as my previous one. Any advice from you guys would be appreciated.

Thanks alot!

No power but it works? What does this mean? It feels slower?

It looks like someone deleted a remap from a system lol. Looks like the torq is gone, doesnt pull like it should when accelerating at the begining...

Maybe you put in a different turbo? I think there are 2 kinds of wastegate versions. There is an electronic one. Maybe the wires for the turbo weren't connected.

No, we put exactly same turbo. Everything is connected. Connected bmw live and checked everything out, it shows same bar's as before. Vacuum is good as well. What could be done to the car? What else to check? Im really disapointed that my car is not pulling well like before ( neck breaker )

Have you pulled codes from the car using ISTA-D or Rheingold?

Can you film a 0-60 to run? This tests gauges where it's at in terms of normal power operation.
