there is the 2011 335is with the n54 and the dct.

Er... If you are in an xDrive (and he is RWD) and he only ahead half a car by the third gear, that would actually mean that N55 pulls harder, not the other way around. xDrive is quite a handicap. On top of that, did you swap drivers and get consistent results?

What is the comparison, that the N55 motor makes less horsepower tuned compared to an N54 motor? That is already a given. An N54 with meth and downpipes makes 430whp+ while a N55 with meth and downpipes struggles to make 375whp.

You're talking about peak power- FBO and meth- we know the outcome, I would love to see a fair, tune only race on video.

The JB Stage 1 was great but Stage 2 pulls like a hell top end. The car just acts like it has a V10 engine in it, Driving it in D mode feels exactly like stock instead of that surge feeling that the
JB stage 1 had. But once you nail it it is a smooth pull you can feel TQ then smooth HP all the way to 6000RPMS.

Overall i love the JB4 Stage 2 and look forward to the meth kit from Terry!

My review was based on my completely stock car with JB4 Stage 2 only.
335i N55 6sp Auto.


Oh wow amazing i just noticed i have been on map 1 this whole time running only 12psi!!!
whats the difference between stage 1 and 2? does it feel faster? what do you mean by the harder pull in the top end? thanks so much for your input

I would like to see this as well. Everyone says the N54 makes more peak power with tune + FBO (meth or no meth), and I'm definitely not going to argue it. At the same time, it's a commonly held belief that the power under the (dyno) curve is what's really important. Oddly, there are no N54 vs N55 videos (that I know of) where the cars are set up similarly with the same tune and the same mods (or no mods).

I had to be a pain again but downpipes alone may throw your results off. I believe his gains are a little larger with downpipes than yours, this truly should be something that is left to tune only.

N55 JB4 Stage 2

All the reviews for the JB4 Stage 2 sounds great! There is a blurd on there about emmisions and emmisions regulations. Does this stage 2 make that much of a change that I should be worried about it?

I did a couple of pulls with my friend, he has a 2009 335i dinan stage 2 with dinan intake. I have n55 x drive 335i with jb4/dp/cp and intake... It was pretty dead even, now I am sure if he put in Jb4 and DP that I would get smoked.

Not that I know of unless you put in down pipes.

135 n55 6mt (Jb4,dp,exhaust) Vs 135 n54 auto (jb4, dp, exhaust) From a 40 roll is basically even I have done it over 40 times. * Both map 2*

On our mustang dyno the difference is only about 10-20 hp+ for the n54 but the n55 torque reads about 10-15 higher.

N55 JB4 Stage 2

Okay, this has turned into a two parter:

1. Has anyone noticed any excessive heat, excessive ware on any of the seals, increased maintenance, higher than normal temps since the install? Thanks for your input.

2. If BMW is selling the 300hp and 300fptq why are most of the dyno results I'm seeing in the 240-260hp and tq range?

dont know about #1 but #2 is that youre comparing BMW's flywheel hp/tq numbers to dyno'd at the wheels numbers. drivetrain loss...

i think my best run was like 276hp/288tq on a stock N54. would have to go back and look at which kind of dyno it was.

I am thinking about getting JB4 stage 1 for my 2012 335I F30.

I am looking for reviews from people with previous model 335's. I am just curious if everyone that had JB4 was still happy with it and had no problems...I hear rumors that running JB4 is bad for your engine, but I do not know if that is true or not..
