lol whattt ??? Oh I forgot your from Lithuania just kidding but as I said again you're most likely to gain HP you're just losing a little low end power, ask people around that switched from dci back to stock and it feels just a little more responsive on low rpm's with stock box, but it's not so bad with dci, worse with CAI

Huh? Can you point to any data for this? Or where are you hearing this?

You get slower response on low end with dci and cai, a little bit there's nothing else I need to provide you with

I'm asking for more info and/or a link to info to back up your claim, in hopes of maybe learning something today.... because currently I see no logic in that claim, and actually disagree with it. So where did this idea come from?

[n54iHPFreaK]

It really does lose low end

who has jb3 or procede everybody uses aftermarket dci, maybe only few with stock intake, dont get me wrong but dci all the way should be installed, without data this post is uselles please provide info from where u got this with pictures and so on peace as i told before i dynoed my car with stock intake and bms dci and my dyno graphs better with bms dci

[Iwantm3]

Correct, I use DCI myself, I'm fully modded, it's just when I had my car stock and not only the 335i, my other 2 cars I had before, the low end felt more responsive with stock boxes, just try and reinstall your stock boxes and you will notice it, check jpslicks posts he has stock boxes installed with his tune just because he likes the low end more responsive, and he's much more experienced with tunes than probably both of us

why your signature sais STOCK? if u are fully moded? your wrote your 2 cars maybe it is not the same like bmw intakes, every car has diferent power and intakes, was it bmw 335? and yes i was driving with stock intake didnt notice anything...

p.s tryed to check jpslicks and NO user was found maybe he is not in here anymore

[Iwantm3]

jpslick , it sais stock because I don't have AR DOWNPIPES CP-E FMIC CM vc2 meth DCI I've sold my jb3 ( never installed it ) and I'm not ordering V4 or forge dvs , I'm stock and will stay stock to keep my waranty, you know what I mean =]

You lose no low end response with a CAI. Less resistence for the turbos to draw air cannot result in less power. The DCI could conceivably lose low end power though since the IATs can get quite a bit higher on a sitting engine. I have not seen data to support this though.

CAI for sure, thanks I'm not sure about dci but that's what I've heard

i heard also a lot

[M3 Eater]

mine are sounding a bit loud on start up as well.... up to 3K rpms. After i reach 200 degrees they are not nearly as loud. If you continue to hear a whistle or while, you may have a boost leak of some sort. I have been working on my charge pipe a bit, taking out my dci and noticed I cracked the inlet on the front side intake where the edge of the pipe rubs on the ribbed inside. Car sounded like a jet taking off and boost was not low.... who knows how much dirt I was sucking in from under the hood though. I used some epoxy and gorillia tape and the whistle is gone.

I try not to boost until after the car reaches 200 degrees.

temp is 39 degrees F in NC.

u mean if i use bms dci then i need 200 °F = 93.33 °C well it should be at least 80c i think its enough

Thanks I will deff double check

[**335i**]

on a start up its normal untill it gets warm up

[Jeff@TopGearSolutions]

I have a DCI guys.... Just for the record. Its good to have an aftermarket intake after 14 PSI generally, stock intake and filter are a bottleneck after that.

[MusclezMarinara]

OP said his turbos are loud

DCIs will do that + the cold temps.

[M3 Eater]

i just meant that my turbos whine a bit until the car reaches @200 F.

After that I hear the whistle of the turbos that is normal when you remove your stock box for a DCI. I also have my sound sheild off too. I love the sound of my turbos... I have new turbos on my 07. I don't think I beat them up too badly yet with my jb3. I have been seeing 17.5 psi on map 8 with my new charge pipe though, was thinking about dialing back to map 7 now that I am seeing so much boost
