From when I looked into this a few months back, Active definitely seemed to be among the best in the US. I wish Dinan would have done something for the x28i but they don't seem interested.

Might be interesting to see if Active had anything to say on the possibility of getting around the vin lock and flashing it with a 130 tune.

The 130i also has a different transmission and rear axle (as evidenced by the fact that it can fit the same Performance rotors in back as the 135i). Probably more aggressive gearing/final drive.

The conversion is hopeless, at least at any sort of reasonable cost. In any case, it's more than just a software flash away.

I checked the N51 3 stage versus a high output X5 N52 on RealOEM some time ago and they were the same. The N51 has lower compression, however, and also smaller injectors. The X5 has the 3 stage and different exhaust manifolds. I think it is rated 265hp.

Somewhere here there are dyno runs for a low mileage N52 with 2 stage intake and they look very very close to this higher mileage 3 stage conversion. The newer engine may have been higher. Hard to compare engines with large mileage differences but it didn't support a large gain for the 3 stage.

I think it is possible to gain horsepower with the 3 stage but only if the tune is good.

What do you guys think is a reasonable expectation for gains with just an intake & exhaust?

I'd forgotten about the transmission differences, from memory the one fitted to the 128i isn't rated for a ton more torque than the engine puts out. The 130 shares the same box as the 135i I believe, and even just visually it's way beefier than the 128i model.

No idea on actual numbers. I've got both the Performance exhaust and intake, and besides the obvious improvement in sound, I feel like it's "opened up" the engine more - made it freer-revving and given it a rawer, slightly rude or brash character. This is of course all subjective - and much of it can be attributed to the exhaust note, which is pretty intoxicating, if you're in to that sort of thing.

FWIW, I wouldn't recommend the intake unless you're also doing the exhaust. The exhaust will sound good no matter what, but I felt I would get the most out of it by pairing it with the intake. The intake by itself? Freer revs, maybe, a slight improvement in engine note - but really not worth the money. I only got it because it was an easy DIY and it looks nice in the engine bay - but mostly because, like I said, I think it complements the exhaust nicely.

Good to know, thanks for the tip. I'd definitely be going for the exhaust first, then maybe an intake later after I get some suspension pieces. I can't believe how good the BMW PE sounds from the videos I've seen.

If you guys can get the 130i spec, don't hesitate.
It's unbelivable the difference before/after detune. (I've got a german 274HP tune

Running on a dyno to demonstrate a change is pricey so I understand why it is rare. Running the "torque" program on a smartphone to get a before and after 0-60 run seems like it would be much cheaper/easier and would still be a way to get some idea of the improvement. I think torque also will tell you what it thinks the hp is.

The thread on the main section with a title like "flat dash" has me thinking. A tablet running on the Android software with a GPS and bluetooth can be had for a little over $200 (like the Samsung Galaxy 7 inch). The bluetooth sender for the OPDII port can be pricey but are also available for $20-30. The software is either free or $5 depending on the version. A mount for the tablet is maybe $50. So for about $300, possibly less, you could have torque running and giving you a bunch more information on your car. Additional gauges, 0-60 time, navigation software if you want to use it for that (although my price is a wi-fi which will not work with most droid navigation software). I'm not sure I like the idea of a tablet on the dash, however. It would be functional but I can't figure a way it would look OK.

Yeah, I agree my "torque" comments are somewhat mis-placed but I think only somewhat. Running software on a portable device is obviously a lot different from installing a 3 stage inlet. I like the threads on that + high performance intake + high performance exhaust but the engineer in me wants some data to show that the hundreds to thousands of dollars had a measurable effect. I'm just trying to suggest a way that data could be generated by those making the mods without great cost.

The calculator at this website:

http://www.060calculator.com/

suggests that 5hp should be worth about 0.1 on 0-60 time for our cars. So 0-60 before and after mods would seem to be a fairly sensitive way to know if we accomplished our hp goal.

I can appreciate the need for proof. Hense why I haven't bought any intakes or tunes.

With Disa there are 325/8 dynos that show 10hp gain and tq gain.
For 128i, there are no such dynos. Nor do I have baseline stats for Tourge software. I do have a dyno(128i + no secondary cat 3" exhaust) as a base.

I plan to do a dyno again, just need to know when the next cheap day is.

As far as my tune path, I dont aim for a number, just going after parts that enhance in way that should have been from factory. ( m3 suspension bits, 135i brakes and 130i power levels)

I know this is old but..

130i has a gs6-37bz - and a 3.46 final drive - 135i has the gs6-53bz and a 3.08fd (manual)

So yeah very different

And no i cannot fit the 135i rears with no mods.. Sadly lol

Ed: a quick google says the mt128i has the gs6-17bg?

Beg to differ with you Bob:

The DISA valve + proper programming appear to be the key.

Chipping the N52 in Europe is common. It looks like all N52s built for outside the North Amercian market utilize the 3 stage intake. The exception of course, in the US are Si designated models, E90 330i, and SULEV equipped cars.

Amen.

Where did you get your DISA, realoem? Would you recommend it over AFE, particularly the Stage 2 Si.
Link: http://www.**********s.com/aFe-Stage...0i-E82-E88.htm
Also, ECS has a "Euro Air Box" for the e90, could anyone chime in on this product?
Link: http://www.ecstuning.com/BMW-E90-330...ake/ES2072577/

I'm looking for a good air-box, but it doesn't seem like a whole lot of 1er's go through with it, just the e90 guys. Any particular reason I'm overlooking aside from the 1 series having a smaller audience? I know the engine is a peach but I agree with andrey_gta's response. 250-265hp please with an N/A snarl and I'm set (Btw I plan on getting an AA tune as soon as the intake is on, performance exhaust will be on by next week! Hopefully that rounds out to over 250hp crank.. I am a realist).

I didnt bother replacing the manifold gaskets, cuz they looked okay and were from a newer car than mine.

Hard to say weather intake > manifold. I do not have any intake mods.

With manifold the car does feel more alive with low end torque and top end fun. Intake manifold took me 6h, that is after I cleaned( water & soap) it and let it dry out.

I would say that both mods are compliments that depend on the time and resources you have to do either mod. I was just excited to find the manifold near my home.

afe SI vs Eurobox:
No idea which is best. Shop around, aFe can be had for lower than Eurobox, especially if you live in USA.

As to why not many 1 series have the intake mod: Cuz we are smarter to spend $$$ on unclear gains . Plus I think 1series are just coming out of warranty in mass and priviously everyone went with BMP products.

performance exhaust ... over 250hp crank ... I am a realist
I am in no rush to tune, my Manifold alone dyno will be in late October. The car feels complete too, maybe because 6mt cancels out bad effects

Many exhaust options if you go custom, but only add low end torque in my case, and maybe 5-7 hp

You're not going to be able to determine HP from torque. My 1M has 100 lb-ft more torque than an M3 yet it has less horsepower.

True, but I enjoy drinking the cool-aid. I'd prefer a better noise and throttle response, and 3-5hp wouldn't hurt.

*sigh* I just miss my intake, cat-back, and flash combo from my Audi (maybe the only thing I miss..?).

Welp, screw it. Injen it is. You're next AA flash.

Btw Andrey, tip of the hat to the 128 "is". I swear I was planning on plasti-dipping the badge black and adding an "is" when the mods are complete long ago. But I'm not nearly as close to that entitlement as you are.

BMW's requirements for ///M badges today are a couple body kits front and back and dabbles of shadow-line between.

I don't care for hating on people with ///M badges or any similar posing identity. I don't care for hating on people period. Every person is entitled to his or her personal preferences and tastes. It's up to you to either let it bother you or not give a fuck, and it bugs me sometimes how much fucks are given to people trying to be different or individual on this forum. Having said that, my car is stock, and personally I wouldn't want to put "is" on the rear until I put a few things into it. Just a personal preference. My opinion means nothing.

Having said that.. according to your signature, I would say you're more than ready. Your car must be a dream in the corners.

Haha, Thanks. I was waiting for people to notice.

Although, I doubt I will be doing any tune or any other mods for a little while, will resume it in the spring.

The tune I see as a finishing touch. Its kind of nice to know that I can unlock more fun.
Now my focus is on maintenance, Brakes( those F30 calipers look interesting, or rebuilt 135i calipers) and lastly suspension (m3 bushings & bits)

3-Stage intake installed today (new manifold, installed by dealer). Got a discount though and hey, a two year warranty too! (3.5 hrs labour to install.) Drove on the highway for 20 minutes under varying conditions: Cruising at 2000 RPM, 3500 RPM, Full throttle accel to red line in 2, 3 & 4th gears a few times, then some neighbourhood driving (hills). And....., well almost nothing to report. I think that I've lost some of the growl from my PI, and maybe the above 4000 RPM acceleration is better - difficult to judge as the PI noise was less but the speed gain in 4th seemed faster. No difference in low end torque or throttle response - both have always been pretty good.

Will edit post with any changes that come along.
