Hello everyone,

Im having trouble figuring out the best order of mods to do for my car. '13 335is manual coupe.

My end goal is to have:
-JB4
-Intakes
-Downpipes
-Charge pipe w/ DV or BOV
-Intercooler
-400whp

I understand everything that comes with modding a vehicle, but want the car to remain as reliable as possible, so with that being said I simply want the most efficient and reliable parts. I hope that makes sense and I dont sound like a complete idiot....somewhat of an idiot I'll accept.

Also, what is the safest % of e85 to do without an aftermarket fuel kit?

[Jeff@TopGearSolutions]

Intake won't do much but sound without a tune.

Downpipes won't do much without a tune.

Charge pipe is just for reliability and sound.

Intercooler is an efficiency mod so there is potential power without a tune and more with a tune.

30% E85 with no fuel mods.

There is no correct order per say but most people start with a tune because it offers the most power per dollar and leaves the door open for future modifications and gains.

Thanks for the info. I was just worried that with JB4 bone stock I could break the charge pipe very soon after. Otherwise, it would definitely be my first mod w/ 30% e85.

Yeah, seems like ISs have mega CP probs. Mine cratered 24 hrs after I went stage 1+ MHD. Previous n54 had stock one for 100K miles.

I would not go more than about 15% add in e85 without logging. And I would still stick to gas maps. Just switch to the 95octane map and still mhd 1+.. getting close to 15psi most time.

Not sure what CP is or MHD... sorry man, Im brand new to this haha.

If you are that worried, then get it along with JB4. There is really no way of knowing how soon it will fail but it usually does sooner then later for most.

CP = Charge Pipe

MHD is a app that is downloaded onto an Android device (phone/tablet) and then used to tune your car with various maps (Stage 1, Stage 2 and E85 maps). It seems to be a preferred tune over JB4 now an is very user friendly. Very simple to install compared to the JB4. There are plenty of threads on here about MHD.

If I was you I would start with MHD as you can run the Stage 1 map completely stock. You will right away notice a difference in power. MHD is quite cheap as well, I think the app itself it $150 and Stage 1 map pack is $50.
Following that I would do intercooler and charge pipe. With the intercooler you can then re-flash to Stage 1+...even more power.
Downpipes come next and then you onto Stage 2+

If it were me... I'd start with MHD tune (it's an Android app. Do a quick search on the forum), then go intake and downpipes, then chargepipe and BOV, then intercooler last. Enjoy

Sorry for the Firehose to the face dude



;-)
I like this one

Yep, good start. Maybe IC sooner depending on where you are.

Thanks for the tips. I have an iPhone....so yeah I think MHD is out of the question.

Writing off MHD just because you have a Iphone is a huge mistake. Almost any decent Android based phone from the last couple years will work as long as it's OTG compatible. You don't need cell service to it, just wifi.

The flasher module, map pack, and monitor module will set you back $220, $45 for a guaranteed DCAN cable, and a new or used compatible android device can be had for $50-100.

This guy knows... I got a Nexus 7 tablet on eBay for 38$

Down pipes will cause major codes without a tune, so perhaps that's last.

The charge pipe & FMIC should be a single purchase. Otherwise, you increase the chances of blowing apart your OEM charge pipe.

Intakes? I think you mean silicone intakes leading to the turbos. They are a PITA, unless you are in the process of replacing the turbos.

If you are talking about DCI or a better CAI, then I'd do that shortly after you upgraded your CP & FMIC. They kind of go together.

[RLe92335]

Im still a novice here but I blew my charge pipe up with just a tune. And having a blown chargepipe just sucks a$$. So while it may not get you any more juice like the other mods do, I would get the chargepipe with the tune so that you can just avoid that issue altogether.

He's definitely talking DCI... I stand by my order. We could argue how important an intercooler is but I say leave it last. Unless you're tracking the car maybe bump it up spot or two

I drove over 30k miles with Cobb AP and never blew my stock charge pipe... maybe that's just me :

We got a few guys a week that are desperate to get charge pipes ASAP cause they blew them up. Not just on this platform but the N55 E and F series.

07-08 years are stronger then 09+, something to keep in mind.

I'm 08 so this is a valid point

No need to make excuses, just get yourself a cheap android device and do it right the first time with MHD.

I guess everyone has there own opinion but leaving the FMIC till last is crazy if you ask me. These cars have weak stock intercoolers and with a tune your just creating more heat. Look at the MHD logs people post on here with factory IC's, their IAT's are high for the most part.

[MSully96]

Thank you all for the input. From what Im hearing...I might be doing CP and tune first, then FMIC and intakes, finally downpipes. I guess the only downfall to not doing FMIC first is higher IAT, but I will definitely do that shortly after.

Yeah DCI for sure.

Last question, Im sure its best to just upgrade the entire intakes - inlets and all, but would it still be beneficial and efficient to just upgrade the filters to cones?

Definitely... I went with BMS dual cone intake which is arguably the most widely used out there.

Awesome. I might go with that (I mean hell for $100 why not?) and down the road go with a full kit... if necessary.
