JB4 Power Gains?

Supahone · 05-08-2019, 08:33 PM

I spent the better part of the day scanning the archives and I did not find clear and current information about the rwhp and torque gains one could realistically expect on a stock 2011 N63 550i xdrive; meaning stock dp, stock intake tubes, stock turbo and on 93 octane.
If any forum member has current quantifiable data that presents rwhp and torque figures can you share that information. Please don't site specs provided by BMS because much of their data is based on 30% E85 and downpipe modification. These days in New England, they are cracking down on catless downpipe mods and ecu codes during emissions tests flagging these vehicles for failure even if stock cats are reinstalled. The vehicle has to be taken to an inspection center and visually verified by a state inspector to have the flag removed. Thanks in Advance.

Thanks for the reply. Any specs on torque output to the wheels?
