Recently installed jb4. Ive noticed after doing a few hard pulls in M mode after i shift up to 6th and just cruise the car doesnt move. I hear the engine sucking in air but the car takes a while to get over 2000rpm. Also in D mode when in 6th and M mode the engine pulses while sucking in the air. I checked my intake everything is sealed and also checked for any leaks and nothing. Anyone else experience that or have any insight as to what might be the problem? Its a 2011 n55 AT w/ alpina flash. Thanks in advance guys!

Do you have usb to check for codes?

[xcxxr335]

No I've ordered one and waiting on it to come in. But ive been checking th codes though the jb4 im just getting a exhaust flap code, and bov/dv jammed shut. Both common codes ive read nothing to worry about there.

In D mode the car will suck in air and stop and suck in air and stop untill i get higher in the rpm range. It pulses and pulls slowly. But in M mode espcially the car is sucking air but taking long to get out of the 2000rpm range
