The guy in this thread Kamfa has a PTF protune with his Stage 2 turbo that put out 450-460whp and 480-490wtq on 93 pump(he's also xDrive). I'd say that's pretty good in line with the JB4 if you're tuning options are between the two for pump only.
I'd start selling the Cobb though either way, make some money back because I'm sure MHD will come up with developments next year by Q2 or Q3 for the N55(IMO that's what I'd do). |

Could I run more that 19-20 psi, nope, DME runs blind. Do I need more than 20 psi for a daily driver, nope. Sadly, I am back in the great State of Montana and the closest source of E85 is a couple hours away so I am back to the JB4 and Meth... I look forward to the day when Cobb supports the N55 the way the N54 is supported.

More like they don't do shite. I went on a letter writing campaign for a while trying to get someone at Cobb to throw the community a bone but all I got in return was "I'll be sure to pass that along to the higher ups." Just tell me to f-off instead...

Probably the smart route to take. I'm stubborn and will probably hang on to mine until it is worth nothing Besides, I see a custom back end flash in my future as the off the shelf JB4 flashes do not work as well on my car as they do on other N55 cars with Pure S2. Now to find a good source of E100 I can have shipped to my house!!

Hey did you guys hear moving forward Cobb is not supporting BMW, specifically the 335 platform? My buddy shot me a thread from n54 tech?

Yes. That's the reason why I'm selling it. I'm getting a JB4 and I'll wait till MHD does something for us to use both in conjunction for the Stage 2 turbo.

Incorrect. The n55 6at uses the same old 6at tranny on the n54... they all start to fail when pushing big power... and no, i'm not saying this because i'm a 6mt fan boy.

I never said we have a different AT than N54s. But how many N55s are over 600whp where the 6AT has shown to fail? An absolutely maxed out stage 2 might reach 600whp with future tuning advances.

Here is an official statement I received from Cobb/Jared this morning: Brian, Truth be told we never tell a customer to F-Off and every single one of the requests for features/additional support, etc, are actually forwarded/discussed and logged. The bottom line is a lot of the general public tends to believe COBB is this huge corporate entity with endless pockets and resources. In reality, we're still a fairly small business with only 80ish people here at our Austin HQ which includes our full staffs for customer service , warehouse, shipping, production, accounting, and finally, engineering. When you start looking at those numbers, you realize we aren't sitting on teams of 20 engineers per platform ready to jump on every request or new vehicle. We have to very carefully pick and choose the vehicles we support and use the resources we have as carefully as possible, otherwise, we won't end up being in business at all. Which...brings us to BMW and COBB's BMW support. The truth to the story here is we won't be adding any additional N55 features or vehicle support in the foreseeable future because the cost to benefit is so poor. The BMW platform is one of our most expensive, research and development wise, to get support up and running for, and even more so to continue to keep support going. Couple that with sales that don't support the resources we have to devote to the platform and inevitable solution is something has to give. I assure you, there are TONS of people in this building who pushed, and still push, for finishing out N55 support for the E9X platforms, getting support for the new F8X M3/M4, etc etc etc but we just don't have the resources available to devote to it at this time. Hopefully it's something we're able to revisit at a later date but with BMW leading the push for high level encryption, providing support and new features for any BMW will continue to be a very expensive proposition with diminishing returns as other market alternatives pirate our hard work and drive pricing down. Wish I had better news for you but if you have any additional questions, just let me know! Thank you, Jared ph: 866-922-3059 web | blog | facebook | twitter | youtube

Think about how many thousands of dollars you are spending on the Pure turbos and other mods. If you buy a Cobb AP + ProTune from PTF, its only a few hundred dollars more than a JB4. It doesn't make sense to cheap out when it comes to the tune. Also, most people who run JB4 with a Pure Turbos upgrade run a BMS backend flash, which means they bought a Cobb AP to install the backend flash. If you are going to buy a Cobb AP for the backend flash anyway, why not just get a custom tune?

for N55 JB4 takes a shit on cobb. i run both using a custom BEF from Terry, if you are pushing the button and running an e50 mix you will get a bunch of codes flash only. houtan has used wedge, PTF and JB4/BEF combo. he has paid for all of the tunes and gone back to jb4. they couldnt get the car to run without throwing codes on e50
