Powerbox 2.2 DTI

Hello together, I drive a beautiful Omega B Caravan 2.2 DTI (y22dth) and am now looking for a Powerbox. I would like to ask you about this before I add one. I have already found googled and various manufacturers. Unfortunately, I can’t assess which manufacturers are the “good” and which are the “bad ones”. In general, I think that the box will not get 200 hp from the vehicle. However, the Powerbox should really be extra power, but also an This is my understanding of extra power and economy. Can you please tell me your manufacturers (module names), performance values and consumptions. You can also call me the black sheep so that nobody shoots the engine. Greetings Schnubbitec
