What do you mean when you say the engine drops? Drops what? Boost? Rpm? I don't have a clear understanding of what you are saying.

From the limited information, try hitting the MAF sensor with a screwdriver, while the engine is running. If it stumbles, that is your problem. Replace it.

Did you set the translator right? Might not be it but just x2 check.
