I couldnt resist...
I had a tune only done bringing the car to 715hp and 1060 NM torque
That was a great improvement to stock and after trying to convince myself it is
enough power i failed and just started my phase 2 of modifications
so this is my current plan:
1) Kleeman spark plugs and turbo/down pipe - catless - already ordered and have it here
2) modify turbos at TTH Hamburg in Germany http://turbo-technik-hamburg.de/ (they do for GTR - 9ff - pp performance and many others in germany use their turbo modifications)
Shops here in Germany like Elmerhaus or Posaidon or PP Performance have used their turbos for their builds:

My car is in the shop already to dissemble so I can mail them to TTH in Hamburg hopefully over the weekend
3) weistec TCU upgrade (to avoid clutch slipping) -*http://weistec.com/all/clk/clk-63/20...u-upgrade.html
this is already ready and shipping to weistec shortly
4) I will remove the stock LSD and have bought a Quaife that I already have ordered
5) AMS cool kit just to be sure temps stay low:http://www.amsperformance.com/cart/a...ler-kit.html*- have it already here
6) individual mapping at seidtperformance http://www.seidt-performance.de/2.html - he individually writes a software for each car on the dyno going through all ignition angles and checking lamba and detonations etc...he is also the one who did my car with only tune - I attached the dyno sheet
i hope things will work out well in that combination - your positive thoughts and support will surely help :-)

I care more about improvement from a roll start 3rd gear around 90 kph and then hit hard and see the results for 100-200 and 100-300 respectively.
I tested 100-200 the other day and my result on a perfromance box measured was 6.7 showing on the display.
Numbers aside the real world comparison is what is more fun.for example the car as it is currently does a drag from 90kph up faster than a brand new gtr but a 991 Turbo S at least up to 230 kph roundabouts is a nose length more in front, I might make it back up if we go faster than 240 kph but we couldn't test that day.

i thought stock they were close, surly moded you win

unfortunately the TCU/valvebody unit broke on its way to weistec by DHL - we submitted a claim not sure how it will work out.
what sucks is I have to order a new one from MB dealership but they have to pair/code it with my car - however my car is in no shape to turn on the ignition for some time... so this really sucks
anyhow - I will get turbos now done, install them along with the turbo and downpipes - and install the ams cool kit and put things back together so I can then toe the car to MB for the TCU/valvebody to be ordered and paired with my car to then send it to weistec again...
only after thats done I will be able to toe the car to seidt performance for the mapping - I hope i can be done with everything early february

wish me some luck and best of success, I am sure it would help - thank you! Shame about the TCU mishap (it will be a funny conversation with your dealer when you order the new part!).
You are lucky you have access to a full custom tune, no such luck in Australia with AMGs.
car is finally ready - result is 820hp and little over 1111NM torque.
I attached the dyno sheet for your reference.
yesterday night I probably did about 20-30 pulls to find out my 60-120 times (in Germany we do 100-200 kph - its pretty much the same)
in any case, the procedure is I do so start in in 3rd gear and floor the pedal all the way up high into 5th gear (as far as I can get
What I noticed is the car would have problems shifiting quick and clean repeatidly and it always only involved the shift from 3rd into 4th .
Let me explain further:
Scenario 1: I would have the car steady in 3rd gear at about 55 mph - hit kickdown - when the car was then shifting from 3rd into 4th gear
it almost felt as if it hit the rev limiter for a moment while shifting - so the shift process was very rough, and actually took speed away before going into 4th...
the shift process from 4th into 5th in comparison for example goes through like a hot knife through butter - clean and fast.
In comparison the shift from 4th to 5th took not even half the time 3rd to 4th took plus from 4th to 5th you would NOT feel any interruption of power
while the shift process from 3rd into 4th however clearly interrupts the power for a moment and feels like a brief moment of hitting the rev limiter
(as if you'd hit the brakes for a brief moment)
Scanario 2: I would have the car steady in 3rd gear at about 68 mph which is about 4,5000 rpm - hit kickdown - and now both 3rd to 4th and 4th to 5th
go through nice and clean and quick
I repeated the above at least a dozen times and always had the same result. I have not done a run from a complete standstill all the way up
to say how the gearbox behaves then - but clearly Scenario 1 has issues. The problem is Scenario 1 is the most common one anyone does.
Because 60-120 mph is like the standard time everyone is looking at to compare pull times - so I want to be able to start below 60 mph in speed.
Problem is when I do so it screws with my shift process 3rd to 4th. Only if I start above 60 mph the shift process 3rd to 4th is clean.
Any idea what I can do? Is this maybe a software issue, should I ask the MB dealer to update my gearbox software?
or can I ask the dealership to reset something (adaption?), so the car could re-learn the shift process - I could really need some input here
thank you!

Video of it on my IG page.
My tune makes much less power than yours. Do you have wheel spin?
I wrote to Weistec, as I have a TCU/valvebody mod from them see what they come back to me with.
What is your IG page? and what exactly is part of the Eurocharged Stage 2 modification and resulting HP?
6.0 is very good obviously!

I'm making 575whp and 705wtq. Regular pump gas, 94 octane. No passenger, 100 lb of weight in the trunk, and heavy cast 20" wheels.
Tune, downpipes, filters, x pipe.

but how where you measuring time?
this is 3rd gear you are starting from in the video, is it?
if it is your shift process 3rd to 4th is much cleaner and faster than mine...
which brings meback to my posting above asking about any feedback :-)
You should be much faster than a tune and downpipe car.
I agree that you may need some tcu work.
Anybody know how they access the tcu? Is it a separate unit?

This is the lit of all I did:
- turbocharger hardware modification at Turbo Technik Hamburg: http://www.ebay.de/itm/Upgrade-Turbo...3D291669507444
- Kleemann Downpipes turbo back catless
- New Iridium Sparks bought from Kleemann, same they sell with their kits
- Weistec TCU/ Valvebody upgrade: http://weistec.com/all/clk/clk-63/20...u-upgrade.html
- AMS cool Kit: https://www.amsperformance.com/cart/...ooler-kit.html
- UPD Cold air kit: http://ultimatepd.com/2011-2015-merc...boost-kit.html
- UPD underdrive crank pulley: http://ultimatepd.com/2011-2015-merc...nk-pulley.html
- UPD idler kit: http://ultimatepd.com/2011-2015-m157...idler-kit.html
- AMG original LSD modified at http://www.limitedslip.de/
- Elmerhaus modified air hoses (stronger from metal)
attached are my dyno sheets from last year with ALL STOCK hardware and ONLY software modification before (vorher) and after (nachher)
so with all stock hardware I was pushing around 700hp and 1060Nm
and after all the above modifications I now push around 800 hp and 1110Nm
I can tell you that I am somewhat baffled by the result which is significantly below my expectations...
car is finally ready - result is 820hp and little over 1111NM torque.

thats crazy for all those mods... for an extra 60 hp above tune and turbopipes/downpipes.
