Next Mod Opinion

[Montego92]

Picked up a BMS Stage 1 the other day for my 2016 that I haven't even picked up yet. I plan on doing the 1200 mile break-in, then install the Stage 1.

Anyway, contemplating my next mod. I'm thinking either a BMS DCI or VRSF catless downpipes. The DCI would be purely for sound, as I'm aware it's not going to make any power. My only apprehension with the downpipes, is that I'll probably be driving around with a CEL for a month or two until I can get either the canflap or the full up JB4. I'm also ever so slightly concerned about exhaust note. The intake would be a simple install.

Which would you recommend?

Get the intake until you get the JB4 or CanFlap module. I would recommend the full JB4, but stage1 with CanFlap module is a popular choice for many guys.

Downpipes will make the exhaust deeper and more aggressive/throatier. Will be moderately louder but not too much, IMO.

Like mike said get the intake and once you get either the jb4 or can flap them do ur downpipes, I love mine I have the same setup downpipes, jb4 and intake. My wife doesn't like the sound all I have to do it's close the valves and it's not as loud. Imo

That's what the sensible side of me says. The other says "Screw it, I want power".

Mods in order imo:

1. Tune ( I went JB4 for long term scalability)

2. Downpipes ( I went ER)

3. Tires (going 295 out back and 275 up front)

4. Intake (I went BMS for sound and price)

5. Meth

= 540rwhp

Would recommend Evolution Racewerks Downpipes and ESS T-500 Flash tune. The flash will take care of the CEL, as well as cold start, top speed limiter and other features.

We're located in Anaheim, feel free to drop by anytime.

Catless downpipes will offer a lot more than the intake. you should definitely get the DP first.

You will need the can flap module to clear the codes or just upgrade your stage 1 to a Jb4

Which tires are you going with. I am going to do the same as 275 out back is definitely not enough rubber.

I would get meth 3rd.

why would you keep adding more power when the stock tires have a hard time keeping up with stock power

i would do :

1)tires

2) flash tune

3) downpipes

4)meth

5) intakes

Because unless the OP is racing, tires shouldn't matter much on the street. Also, you can't get meth if you get a flash tune. Unless OP wants to spend $700-$800 on the HSF-4 AquaMist kit which is pointless.

[Montego92]

No racing, just cruising around Germany. The two choices are either VRSF Catless Downpipes or a BMS intake. I haven't even picked my car up yet. I get it next month.

I really don't want to mess with installation of JB4, so I'll probably just stay Stage 1 with the CANFLAP. That is until I get "sick" of the car at some point. If I get the downpipes, I'd probably be driving around with the CEL for a month or so.

As I understand it, the CEL will have no adverse effects on mechanical operation. Rather, it'll just be an annoyance. Correct? No limp mode or anything?

Thanks!

I am going Michelin PSS. Then swapping my 275 from rear to front.

You can always get meth even if you are running a flash tune. Progressive controller is all that is required. Most meth kits will run a minimum of $600 anyway.

you can absolutely have meth and a flash... i had meth on my b8 s4 with a flash tune and might do meth on this car at some point

tires are the most important part of the car and i regret not having them as my first upgrade

Like I said, its more complicated. JB4 is simple and has been around for 7-8 years. When adding meth for a flash, you have to take the DME out again and have the tuner tune for the increased in octane.

In addition, the only SAFE way of installing meth on ANY car is by physically connecting it to the car + the tune itself. The JB4 does this because the JB4 is able to analyze how the car is running and then control meth flow as a function of that. You cannot do that with a flash. You can't even do that with the Aquamist. Those progressive boost controllers that exist, yeah they're OKAY but they are a secondary system that has to work with a primary system. With the JB4 on the other hand, the meth system is part of the primary system to begin with = SAFER.

So yes, you can run meth with a flash. But is it safe? Are you able to tune the car yourself (b/c of nonexistent OBD II flashing) for the meth? NO.

[Irishace]

Cobb systems easy allow you to tune for meth.

That said, there is also no need to tune for meth and it is still very beneficial. With the s55 the dme will add timing with the higher octane detected from meth. We saw this on the N54 and we see this here when folks run race gas on the S55. Also, the reduced IATs alone will significantly enhance performance.

The JB4 just simply adds boost into the equation. While I agree the JB4 meth integration is just awesome, there is still significant benefit to running meth in a flashed car even if you can't tune for it per se.

Meth on the S55 does absolutely nothing for the IATs. The stock cooling system was so well put together. On my N55, there was a sharp reduction in IATs when meth was sprayed, not at all with the S55.

Also again, Cobb has OBD II functionality. The current flashes for S55 do not.

I do agree, current flash landscape is limited to bench flashing for S55 but yiy would have to agree that the octane increase from meth is a big help even to a bench flashed car. I also agree that the cooling system is really quite incredible on the S55 but meth will still provide assistance in that regard. I will be heading down the meth path when a reasonable charge pipe solution hits the market.

There are a few guys running meth, so I am going to see if I can get them to log IAT suppression with and without meth flowing.
