Nice gains , Enjoy.:thumbs:
well done man , nice power, enjoy it!:thumbs:
just a quick question as there seems to be quite a lot of Xcede supporters here, maybe you can explain this to me and anyone else that's wondering the same thing. This car has SW and DP and is pushing 234wkw. ive been reading race tales on this site for ages and I've seen Andz say a couple of times that his car pushes 260wkw at the reef with just software. no DPs just software. so whats up with his software that its pushing so much more power? 26 wkw is a shit load and no other mods. is it just a seriously aggressive tune? if it is whats that gonna do to the internals? if its not doing any damage then why isn't that map being loaded onto everyone elses car?
I really mean no disrespect to the tuners I just cant seem to figure it out and no one else asks... If someone could pls explain I would appreciate it.

good question. i have also always wondered.
i think when Andz gets those figures he is not on pump fuel and has an aggressive tune. i dont see him getting those figures reliably with software only for every day driving on pump fuel but then again i am not an expert :dunno: we can just surmise until the experts confirm.

Like dvst8 mentioned mate. lots of factors. I had a mate at work who recently parted company with his 135i. Just before he did though, he had a serious meltdown and had almost a full rebuild done to the engine by BMW, and before this happened him and i would pretty mucck when doing some runs on the highway, give or take a nose here and there. After the repair though his car was super strong. The type of pulling power we would all like to have over the next X35 driver. Reason being is that parts are tweaked by BMW through their lifespan. So a vaccum pipe from 2008 is def not the same as a 2013 vaccum pipe for instance. And the same applies to the turbos, internals, charge pipes, manifolds, etc.
Our cars are also not AMG's with supposedly hand built engines by an individual person but like GTR's, no two X35i engines are same, so some cars are stronger than others coupled with dvst8's explanation, its just the way the cookie crumbles.
Either way im ecstatic with my car and the power its pushing. Again for me kilowatts are important but torque matters most. We have so little road to play with, so you want to gobble it up quickly. Quick = Torque
Hope this helps. Source of info (just my opinion and what one of my BMW mates explained who works at BMW)
Well done DJ Noly! You rocking the dyno there!
Ok good question. Unfortunately the answer is not so simple. Power a car makes on a dyno can vary depending on:
That's just off the top of my head while I'm sitting here. There are much more.
The map on the cars are the same, the difference is just a combination of what I mentioned above. And nothing will happen to the "internals". There are cars with 700whp running on stock internals. The N54 has forged internals anyway, it's a car that leaves the factory designed for boost & the same "internals" as a 1M that makes almost 250 wheel kw stock. The N54 has been out since 2006 & I don't think there is a widespread problem of damage to the engine.
Ok so let me state something & I'm going to repeat the hell out of it so that there's no confusion.
Andz was on a normal everyday tune.
Same tune Gideon from this forum had for the past 2 years and over 100 000km of chipped driving. Driving to PE couple times a year, going racing & driving hard for 100 000km chipped. And Gideon made 265kw on the wheels on the same dyno with SW & downpipe.
And besides Gideon there are probably 30 cars that made between 250-260 wheel kw & drove their cars for a few years. Kabir is also on this forum & also made over 250kw with just sw.
I don't understand where this paranoia is coming from, are there N54's with blown engines lining up at the dealerships? There are known issues with fuel pumps, injectors & wastegate rattle but there are no real issues with engine problems from tuning the N54. Unless I been doing this since 2006 & someone forgot to tell me N54's are blowing up from chipping.

- Ambient conditions (temperature, humidity, barometric pressure, etc)
- Fuel quality
- Fuel octane
- Dyno variables (roller weight, roller condition, roller lubrication, etc)
- Temperature of engine at time of run
- Variables in engine (plugs, fuel pressure, wastegate stiffness, etc)
- Drivetrain friction (gearbox, torque convertor, diff, etc)
- Engine friction
- Engine condition

As Sherwin states.... the engine is bulletproof.
It's the surrounding stuff like injectors, coil packs and the lot that don't last.... but they don't last on stock std cars either

speaking as a man on the street with limited knowledge. who is going to go to the dealership and put their hand up and say my cylinder head cracked, or my car broke because i had a tune on it? i know i can get 265wkw on my car with tune only, but at times it goes into limp mode which in my understanding is not good for the engine. and yes my cylinder head and a whole lot of other stuff broke. was it due to me putting too much stress on the car with excessive boost? perhaps, wtf do i know, but i am not going to tell the dealership that am i. we just trying to learn here so we can enjoy our tunes and not stuff up our cars. has Andz experienced any problems with his car? we all know the risks of tuning, but we trying to make it as calculated as possible hence the questions which you might feel are dumb, but to us they aren't. dont worry, i know how you feel, i deal with stupid questions all day in my line of work, but i deal with the questions differently.

Ok fair enough. So there are no cylinder heads cracking. Zero. Since 2006, zero documented cases of cylinder heads cracking that I know of. If someone else knows of any, then please come forward for the sake of the community.
I think the fact that the N54 has a forged steel Crankshaft & forged cracked connecting rods and forged Mahle pistons.
Andz, has had an intermittent problem for quite a long time & it ended up being injectors. Apart from that no issues with the engine.
Here' another car that went from 204kw to 261kw on wheels with sw only & on pump fuel & is still driving fine after 2 years:

Is that an N54 Sherwin? Makes its power quite high up in comparison to other N54's. 260wkw is mad!
