Found horsepower and torque for X5 diesel

[centrofly]

Any Diesel guys out there interested in going from 286 bhp to near 390 bhp
and ridiculous torque. I just found a UK company that looks like what I am going to implement into my X5 after my break in period. Spoke to my boat mechanic yesterday told me that the engine will run smoother and better gas mileage (if you dont step into it) but with more horses than BMW wants you to have! He has a duramax diesel 6.6 liter with bullydog program that has three settings calm, fast, scarry. He tows massive boats with that diesel and has over a 110,000 miles still running smooth. Went for a ride with him and was not BMW luxury but damn fast! I will provide more info whoever wants it.
