I haven't had a chance to remove catalytic and measure the turbo outlet. I know that the n55 prior to 07/13 had a 3.5inch turbo outlet. Does anyone know if the n55 on the 235 has the 4 or 3.5inch? If you look at the Dyno results on burgers website the 435 n55 makes more power than both the 335 and 235 n55 (235 obviously being produced after 7/13).

Do you know why they aren't making the same power with the jb4 with the same applications?

The 435i there was running a kill mode with E40 fuel.

The ewg cars have a stock turbo with bigger compressor wheel. This allows for more power in the upper rpm.
