Mission Performance dyno tuned Stage 1 to 678whp/645wtq

Hi everyone,

I am a fellow enthusiast who somehow cannot find satisfaction with a 560hp car, lol. Even though I will never realize the full performance potential of this car, the power/weight ratio has me wanting more. This is my first BMW and I'm happy to discover that the s63tu engine is so reliable and so accepting of modifications, that it was a no-brainer that a flash was in store.

Enter Mission Performance (Alex and Kareem). Its a funny coincidence that they introduced themselves to this M5 community about the same time I picked up my 2014 M5 a few months ago. As a result, I didnt pay much attention to the "new" guys as I researched which tuner/flash to go with. Those who've been on this forum for at least a couple months will know that there are only a couple big name tunes that most go with, rightfully so for their service and reliability (based on member reviews). And I did call a few to inquire. But, after multiple messages and some phone calls, something drew me to Mission. Those who have spoken with Alex may be able to detect the passion behind his work and explanations. And because they tune other BMW models, my research branched out of the M5 forums, to the conclusion that Mission stands behind their work and can provide top shelf support.

Anyways, lets get to the good stuff. This is a stage 1 (or 1.5 I guess) tune because I'm still on stock downpipes. I have the following on my car:

Corsa mufflers
Stock DP
BMC filters/ charcoal filters removed.
AP air scoops.

From day 1 I told Alex that a simple flash will not do. I've had tuned cars in the past and wanted my flash to be dyno tuned specifically for my car with slightly more power than a typical stage 1, and to smooth out power delivery. I'm not sure how complex/sophisticated BMW ECUs have become, but I was set on my decision and willing to pay a little extra for it.

I arrived at their shop last Thursday and had the flash done. Immediate test drive impressions were just Holy Sh*t type of reaction. Those who had flashes know what I'm talking about. This car is really awake now!! Boost hits harder ~2.5 to 3k rpm and bye-bye traction in 3rd (ran out of road to test any higher). Alex recommended I change and gap my plugs to 0.022 since the ECUs are out anyways and I'm at 22k miles. Ok, sure, but spark plugs for the M5 are not in stock that day. Apparently 550 uses the same plugs as M5, without the M logo and $10 less/plug, so we go with that.

Everything is good and I leave to drive home. Get on the freeway and floor it and BAMM!! Drivetrain error light comes on and kicks me into limp mode; exhaust sounds different on passenger side. Imagine if I had shipped out my ECUs to flash and would have to troubleshoot this on my own. I get the car back to the shop and its immediately diagnosed as a misfire. This is when the support of your tuner makes all of the difference in the world. I expect a plan of action to correct issues without any finger pointing, and Mission did just that. They immediately take things apart again and test plugs and coils and we found out my #3 coil went bad. They replace it and everything is right in the world again, a couple of test runs and car runs smooth and I make it home (in traffic though).

At this point I havent dyno tuned yet and not sure what my power output is. Mission was having a dyno day that Saturday, however, I work Saturdays....dilemma. I'd have to figure out how to coordinate another dyno day, probably when my wife and kids have returned from their long summer trip (ie. not gonna happen). So I call my receptionist and tell her I wont be in Saturday and problem solved (priorities, right?).

I arrive on Saturday and am first up. I should also state that I run 3 gallons of E85/tank regularly. Alex flashes back to stock to get a baseline run in 4th gear with speed limiter. Result is about 550whp/500wtq avg over a few runs; typical numbers for stock. Stage 1 is flashed again and all future runs are done in 5th gear. Throughout the session the M5 was having traction and heat soaking issues. But a couple hours and 22 runs later we arrive at 678whp/645wtq and a smoother power delivery. I asked Alex to keep torque in check so my clutches dont fry, but I'm still having traction issues and have 305 pzeros en route; hopefully will help a little.

I hung around for a couple hours afterwards talking shop with the other attendees. There was a manual 535 tuned to 500wtq (stage 2)!! Mission's own shop 550 put down hp/tq numbers in the 500s on stock DPs too.

Anyways thanks for your attention and I hope others here can benefit from my experience. Apparently anyone can flash our cars, but find a tuner who can get into the flash tune itself and stand behind their work.

Very nice! Congrats, those are very solid numbers.

I just had mine dyno'd at HG Motorsports. Was a little disappointed with JB4 + BCM on Map 1. I'm sure Map 2 and better fuel/meth would show better results, but this is my daily driver. I'll ask you a few things via pm...

I have K&N drop ins and muffler deletes. That's it for performance mods.

602, 590, 582 all in 4th gear. Tech said might be heat soak or ecu didn't like the piggyback so pulled timing on top end. I will do a write up later with graphs and all.

I couldn't even log the runs because the Bluetooth JB4Connect wouldn't work...ugh. So disappointing. I need better fuel and/or meth. Or just a tune and downpipe and be done. I would say jb4 is good for logging and analyzing runs, but I couldn't even get that.

You need to make logs and adjust your mapping on the JB4
If you have not done this, then this is the reason why you are not making great gains.
The selective maps 1/2/3/4.... all need to have adjustment's to get the best performance.
Even with Meth and E85, still need to make around 10 logs or so and you can fine tune the JB4

Low 600s normal on Only BMS stage 1. I did similar. I did exactly 600whp and 600wtrq

On to JB4 with BCM I did 620whp and 630wtrw but holy hell did I pickup a mountain of power under the curve.

Now I have backend flash with the Jb4+BCM combo and will be dynoying this Saturday.

I found Jb4 inconsistent becuase the stock fuel trims where not allowing it to really go!

I was told 22psi, which sounds about right? I dont think you can go higher without stacking a JB4? I dont need anymore power with my fairly stock setup. I do want to cool/clean the intakes and fight the heat soak, so I'm looking into water/meth system....

It is possible.
I know of a few California S63T engines running in the low to mid 670's on just a flash tune and downpipes.

My opinion is that at that power you need really need upgraded clutches to be able to really enjoy the power. Clutches will slip for sure soon enough.

When you were getting adjustment's to the ECU files, did they have to remove the ECU's each time ?
Were they opened or drilled ?

Awesome performance gains !

Your numbers sounds normal, Im not sure where you live but in this heat and back to back runs the power loss is normal also

The initial bench flash on Thursday was a drill. But he also loaded a software call Mboot which allowed him to do flashes via OBDII. So on dyno day he just hooked his laptop to the OBDII port and flashed different tunes as he made adjustments....no more ECU removals.

Great numbers. I've been seeing some great numbers lately on stock plate forms. I saw a dyno on another car (diff tuner) did 690w with stock Downpipes and exhaust. Insane.

Congrats! It's a huge difference and a totally different car

Yes that is correct.
They would have to install a boot loader and you should now have a VIN specific cable to be able to flash your DME's thru the OBD port
But, that may only be for their software...I'm not 100% on that.
Too bad they had to drill the ECU's.
Would of been nice if they could of opened them up the initial time instead of drilling.
But those are great gains regardless.
Congrats !!!

Good stuff apexlocator your car will adapt so your your final WHP numbers should be slightly higher. The M5 is no sleeper, but now you've got a rocket ship!

That was offered as an option, but I was told opening the sealant material caries a higher risk of internal damage??...I don't know...

I'm still amazed at the number, 678 w/ stock dp's. Did they say anything about going catless? Don't the turbos run a bit cooler if you remove that restriction?

Does Alex charge extra for minor adjustments, for example going catless (cold start delete and CEL removal)?

Thanks for the write up and follow up messages offline!

I feel this is a topic that will get mixed reviews.
There is a specific sealant that is used. It is readily available.
Personally, the idea of having the possibility of small medal shavings with even the slightest chance of being inside the circuit board worries me.
Regardless what type of machine / vacuum is used.
There are tuners drilling and there are tuners opening ECU's.
As long as the tuner guarantees that if there ever is an issue with the ECU that they will back the customer up, is the only thing that we can hope for.

Only extra cost is the Mboot.

I'm realistic, I know the turbos will run a bit hotter with the restrictions.
I had actually, and reluctantly, decided to go catless DP before all of this and was looking at a local set FS. It was an internal struggle for a long time, lol. The wastegate rattle was my biggest gripe, followed by the smell. Alex said he has a way to tune out most of the rattling, and it was worth a shot.

But I snoozed on the used DP and it sold. And I'll never pay retail for catless DP. I can't be alone in this, but two pipes with o2 bungs should not cost $1500+.
