Talking 328i N20 muffler delete okay to run jb4 map2? - 05-04-2018, 10:45 AM

Hello,

I recently got a muffler delete in my F30 328i ( which has brought the car to life) And i was just wondering if it'll be okay to put the JB4 in map 2 or should i wait to get the ******* **.

Definitely wait until you get the kittieless ********* because the c a t s are the most restrictive part of the exhaust with a turbocharged platform and while a muffler delete will free up some back pressure the d p's are what put the most restriction on the turbos. Map 2 is setup to not have that restriction
