BMW S63T4 F9x M5 M8 X5/6M

Great power requires great control

BMW S63T4 Engine found in F90 M5 F92 M8 F95 X5M and F96 X6M can produce up to 950+HP and 1400+NM with factory turbochargers. You are not able to max out stock turbos with stock bottom end rotating assembly because of factory con-rods being limitation with these engines. It is very important to keep torque curve in check. We use our proven strategy on over 100+ M5’s tuned globally. All the torque and HP is moved up top to keep the factory con-rods healthy. Also this is the reason why you do not want to go with upgraded turbos with the stock engine unlike its smaller 6 cylinder brothers.
