JB4 on 335is DCT

Mickey D · 04-18-2012, 04:39 PM

I have been thinking about adding a JB4 to my 335is, I'm not planning on adding any more upgrades. Is it safe? Do i have to worry when i take it to the dealer for service? What kind of gain will i expect to get? Does it effect the power band? Can the DCT handle the upgrade with no issues? I would really appreciate all your comments

If it is just a tune, go for it! It is very easy to take on and off, Jut remember to take off the tune before taking it in for service. Yes it will add quite a bit of power. You will most def enjoy it. The dct could handle the tune only power.

and by the way the 335is is the n54 engine.

Just remember the 335is has the N54 engine so you need the N54 JB4 for that

I have a few customers with the IS running the tune and they love it.
