Have power pack opinion to jb4 - BMW 3-Series (E90 E92) Forum

Twnturbofanatic · 01-28-2013, 01:04 AM

Hey guys just bought a 2010 335i and it came with the bmw power pack. Now I know it's a moderate stock tune but my question is if I go jb4 will I notice a big difference since I already have the power pack tune. Also is it a pain to take off when you go in to the dealer for service? Thanks.

You will notice a difference with a jb4. Are you sure you have an N55?

Some people think removal of a tune is a breeze and some make it out to be the end of the world.

A proficient person can remove it in about 20 minutes.

You should have an N54. I'd look at Cobb if you want ease of install/uninstall.
