No matter how good of a tuner you have, its impossible to defy the law of physics.

Probably a used car that previous owner upgraded wheel

Congrats. If you wanna race it pm me you can test against a few others

I would not take the final figure as gospel.

As always final dyno figures are meaningless unless viewed as a percentage gain over stock. By the looks of things this car netted a 90wkw/200nm gain over stock, which translates to roughly 40%.

Without getting into a debate about whether 40% is realistic that should be your basis of comparison for other results.

I dynoed at SR this weekend only managed a 290atw with same mods,was done on map 7,hoping to go back and try a map 6,but doubt it will net me another 30 wkw...

Congrats....... would be keen to test against you sometime to see the difference on the road if you keen

Hey man
I was there also for the dyno competition.The car kept spinning on the rollers for some reason but I managed a 315wkw and 720nm after we got in the boot.
Sure we can test the two against each other.Did'nt you drive the white M135i?

Why would you say that?
I posted all progress of the car since the start.My first dyno graph was on par with any other EWG M135i.

No offense but ask any other M135i owner. Its not possible to do 320wkw on a stock turbo. There lots of factors to take into account :boost pressure, timing, fuel pumps etc

The stock turbo is not capable of producing this , its not something Im makjng up, this is determined by the size of the compressor wheel

As i mentioned prior, if its a used car , previous owner possibly upgraded the wheel which to you is a bonus.

Hybrid Turbos meaning upgraded wheel compressors on most dynos make 320wkw-330wkw , tuners on this board can confirm this. Xcede Performance have done welll over 20 of these cars with all the same result

What i can suggest is maybe post a log, logs will show whats happening as you say you running standard tmap which is capped at 21psi

hope all this makes sense

Also please dont get me wrong, your car is strong and Im very happy for you. Just rather know your car as opposed to seeing high dyno numbers and calling it stock

;)

similar car , same tuner
