Haha yeah idk if this is accurate or not but maybe as you said its 370, don't even care since its not WHP

PWG and 91oct is the worst possible combination for a 'tuned' N55 F30...

You're right, it's PWG and 91ACN

Look at those pulls on the dyno how they ramp up all weird, something weird was going on for sure and is likely related to the tune.

I want to but the logs are in WP8 file format which opens up only in Dynojet's native software and I wasn't able to properly convert them in CSV format to post on Datazapp

Surely u have other logs of the car. Doesn't need to be logs from the dyno run

Agree that the numbers look far too low.

OP, if you logged using bootmod3, go to the datalogs screen, click on the drop down menu at the far right of the log, click share link, it will open a pop up tab (make sure you disable 'block popups' in your browser) and copy and paste the link of that pop up tab.

EDIT: saw you didn't log with bootmod3 for the dyno runs, but any logs from another time are better than no logs.

Those numbers are low. A stage 2 PWG stock turbo should be at least 340-350+ on pump gas. I did quite a bit more on my last dyno with the stocker so I'm even being conservative.

2013 F30 335i 6MT - Stock PWG Turbo, FBO, 93 octane, BM3 S2 v6 map
Best Pull: 383whp, 494trq

Logs look pretty normal to me for stage 2 stock pwg turbo, aside from high wgdc in upper rpm range that is odd

Is this ots v7.1 91oct map or acn91 map?

Yes sir, it is ACN91 OTS map

Edited to add: Maybe it's the boost that is being pulled.

JB4 out of the box @ 94 octane

BTW not sure how you are getting 378BHP @ the crank out of those numbers.

Boost and timing look decent, at least acceptable and on par. I don't like how WGDC is at 100% up top and boost is only 11 psi or so. Seems like the turbo is overworking quite a bit, possibly a boost leak. PWG turbo should only be in the ~70s or so on S2.

I'm not an N55 guy, but I don't see anything out of the ordinary that would lead to low power numbers, but hopefully someone will come up with something for you.

But it still doesn't equate to how I made about 30-50whp less than I should've, correct?

I sent it to bm3 people as well so curious to see what they have to say about it.

[F30_SixSpeed]

Can you get dyno graph in STD smooth 5 correction factor? I see you have uncorrected... was it very hot that day?

Yeah I can request that to the dyno shop. Actually no, it was about 55 but inside it does get hot sure, after I think 4th run, car was heat soaked but either way, we didn't make more than 315 and lowest 302
