It's an N26? You will find yourself with limited options, I think, especially as the 4WD will rule out a few, such as performance suspension mods. I suggest talking through your options with a really reputable indie tuner shop. I can certainly recommend one in L.A. Best of luck and keep us posted!
Thanks for the input and,yes it's a n26 and I do have xdrive I'm in the Chicago area

You may want to talk to a good tuner if you want to find out how far you can push it without breaking your manufacturer's warranty if that's an issue. The problem is that no tuning product design shop has a business plan that justifies much time spent on developing 50-state legal products for a SULEV engine that only exists in about three states (I believe). You will have to get past the N26's self-imposed restrictions if you want to jury rig something like a Dinan S4 Big Turbo tune designed for the N20. Dinan will wink and tell you it's possible but I wonder if they would allow their vendors to do this to your N26.

Well I don't think the Dinan performance suspension is offered for 4WD but I cannot speak for other products. I have to say, I am not optimistic. If you really want to tune your car very aggressively, I am afraid you have the wrong platform. I am very happy with the mods I've done on my N26, which now has all the performance I need for the street but I have to say -- sorry -- that the performance suspension is the most radical and transformative mod I've done and the one I appreciate the most, as much as the tune. At least you can still do a N26 Stage 1 tune, which is well worth it. The Dinan tune is very high quality and the way it tweaks boost values is really effective.

so this is what I have put together for my "build" remember I'm looking to keep it a daily driver but add a little more power to it. ideally I want to get it to 350whp but it's looking like a pipe dream please give me some feed back thanks
these add ons would put my 2016 228i xdrive at
base
240 +(59)=299
dinan said stock is
261+(59)= 320

Looks like a solid build, I don't know about the cat though. Make sure you do good research on that.

I don't know who to belive, I think your best bet is to do before and after dynos.

I think you will be very happy with the gains either way.

Thanks for the input and yeah I'm questioning the cat back to I'm just trying to squeeze as much HP and still keep it as a daily driver so it's not a pain to drive

Stock (crank) rated is 240hp. Baseline stock wheel hp is more like 228hp. The 240 is under-rated or the parasitic loss is like 5% (not likely). A Dinan Stage 1 tune gets you about 39HP..(not 59 net) so you're around 267whp. My car with just a mild Stage 1 puts out 248-250whp and 317wtq. I wasn't looking at wringing every last possible HP out of the tune as I wanted some built in safety. I doubt you'll ever see 350WHP on the N26 for any length of time (read =Kaboom).

The N26 is the same as the N20; the only differences really are the more restrictive Cat(s) that supposedly pull the power down. I haven't seen an N20 dyno that says it's significantly more than an N26 honestly. The rest of the parts on my car (hoses, etc.) all say N20.

Catbacks are a waste of money on stock internal engines if you are looking for HP increases. If you want sound, buy an axle back system imo.

so your telling me I'm not really losting out on having the n26 vs the n20 engine. Everywhere I looked everyone was oh the n20 is the best its comes from the "n54/n55"and the n26 is a waste of time... I was like WTF but now knowing I can tune it and have some reliable long-term fun with it. I can live with that now I just need to look at breaks and suspension setup. any tips on those two???

I don't really see the N20/N26 comparison as being a big deal. As mentioned, its the same engine with a higher restrictive Cat/downpipe being the biggest difference. As for suspension...KYB shocks/strut systems seem like a popular upgrade. Brakes can be upgraded for about $2200 to the M-performance setup but I think just changing to a higher performance pad will net you the same improvement. I have stock base brakes and they haul my car down from speed pretty fast...

228i vs 240i

Ok so I made the mistake of test driving a 240i
I currently own a 2016 228i x drive and it's ok but is there any chance I can get the same thrills from my 228i x drive that I get from the 240i drive

You can't use 240 from the factory, then add 59 from Dinan. Those numbers are from different dynos in different conditions. What I'm saying is that you can have 3 different dynos and run your car on each one, on the same day, and get different number from each.

Everyone says BMW underrates HP, but look here... http://www.2addicts.com/forums/showthread.php?t=1334063 ... this European dyno basically says the factory number is right on spot.. 240hp and a corrected hp (how ever they calculated it) 244hp.

If you have enough $$$, sure you can do it. But do you really want to spend the coin to get there?

so

so I should find one dyno and do a base test them go from there??? I'm mostly looking for more get up and go from the engine. I've found that I'm certain road condition intersections and filling that gap when changing lanes there's a lag and if I have it in sport or sport plus the engine seems jerky at times

Yes, use the one dyno, and try to use it when atmospheric conditions are as close as possible to your baseline. To be accurate, you need to have all conditions are close to being the same as possible, to see how much a given mod effects the power.

If the stock base HP rating is actually accurate then the 240hp rating and the 228-230hp my car achieved equates to a parasitic driveline loss of just about 9.5%. I don't think, as good as the ZFs are, they are THAT efficient...which is why we all say the 240hp is underrated........
