Thanks a lot

I suggest you take the time to learn about your car and the JB4. Explaining toy you the meaning of parameters will not be of any help if you do not know the basics on tuning these cars.

Well I tell you what......I do not have a JB4 but a dedicated stage 1 and it shits n gets all the way up. really makes me happy and mine does not have the boost bumped up

don't u feel that from 4th gear and up, its weak?
for example :
my friend got wrx with 350hp and when we compare them from about 80 kph (50 mph) , he is stronger

[horsepower_and_hounds]

There could be other variables effecting this also. No I don't find it soft but then the dedicated stage one also only gains me like 30-40 reality hp I think anyways. Awesome upgrade for less than 400 bucks and strong reliability/drive ability.

on jb4 website, it says it gains 60 hp

[horsepower_and_hounds]

I am sure that is perfect condition, on the dyno, good gas, etc. Don't get me wrong I am 100% satisfied with mine 40 or 60. I just did some calculations from the multiple dyno's people have uploaded and it seems they see on an average of 40+ RWH so i always reference that . Either way this compact heavy puppy goes like a scalded cat

Or get RaceChip Ultimate like this group of M235 are using http://www.2addicts.com/forums/showt...091661&page=22

He is getting ~4 psi boost increase across the RPM range . The RC will not add any additional power.

I recommend you contact Burger Tuning technical support ( jon@burgertuning.com ) and send them the log. Maybe you are having another problem that we cannot detect but they can.
Your boost values are good so we know 100% the JB4 is working as it is supposed to.
Maybe you are just expecting too much from 4 psi increase

Why don't you read the numerous threads about the jb4 and get an understanding about it and tuning in general. Educate yourself on tuning, like what's it take to run boost 8 psi over stock, and figure out a game plan on what your looking for. Going into this blind us a good way to really screw things up.

I've seen you on n54tech with this same thread, sorry you're having issues. But, you should look into just getting a stage 1 tune of some sort if you're not going to do a downpipe. BMS Stage 1 or the Schorcher by afe are good options for you. Just simply plug it in and don't worry about making any adjustments because the tune doesn't have settings.
The language barrier might make things harder for you, especially if you're having tuning issues with a more complex tune like a JB4.

oki will tomorow downpipe.
wich one will be better ?
ER - Competition Series 4" Catless Downpipe
or
Mike’s Custom Cat-Delete DownPipe
??

Mike's custom cat-delete downpipe ?

Get the ER downpipe, they are proven to fit 100% and will give you a noticeable increase in performance and sound.

I don't think it says that it makes 60 whp on map 1 specifically.

You can get away with an intake and map 2 if you run 93+ and see numbers closer to that. You'll also see much more boost running map 5 (autotune) vs. map 1 with good gas.

Agree also keep in mind that Burger Tuning like every other company is advertising maximum gains in perfect condition. I for example live in Vegas and cannot expect to pull same numbers on the dyno as Burger tuning sea level dyno in California with perfect dyno weather

This reminds me of the 2009 GTR that was advertised to make 0-60 in less than 3 seconds . They forgot to tell you that in order to get it this fast you need to use launch control which causes you to lose your warranty and damages your transmission
