It's CF vinyl that I purchased online and put on myself.

That's what we were saying...that car is incredibly high-powered for a stock CLS. But the owner said it's bone stock.

Off the shelf tune--Kleemann K1.


It depends on the dealership. There are dealerships in this area that installs and endorses Kleemann products. So, having it flashed by Kleemann would be acceptable at that dealership.

That's the other interesting variable in this comparison. Superlubricity babied his car during the break-in period with mostly freeway miles, whereas I drove it hard. We were interested in seeing if driving it hard during break-in would result in higher gains from ECU tune vs. babying the car. It came out to be roughly even.

Great results!

I'm getting a custom tune done tomorrow by Eurocharged
and I hope the results are similar.

I am taking everyones comments onboard about my CLS.
It was run on the dyno with the 20" vossen wheels on it.
I was told when I purchased the car that it was used by a business person locally just to and from work. It is from a local MB dealer from whom we have purchased a few cars and they are not keen on mods to their vehicles. It was sold new by them. When I bought it is was CPO'd and totally stock in appearance. I received some of the maintenance sheets as well and had nothing to indicate it had been modified. I did read somewhere that RWHP could be pretty good ... maybe here;

I also have a Kleeman catalog that says the stock CLS55 is 476hp. ... either way that is still a big difference.
Not sure what to think now.???? if it does have a tune and has been CPO'd by the dealer then I guess I don't have any warranty issues. Who knows?
Just thinking out loud here.... do you think the lower tire sidewall size results in a lot less tire flex and more power down? (couldn't imagine it helping more than a couple hp).

I wonder how much better a custom tune would be, considering they loaded up a tune for 91 octane as oppose to 92 octane.

James@ACG

The ECU would be able to adapt, on the 6.2L AMG motors a custom tune honestly will not benefit much unless the base tune starts off as crap. As you can see on the these two tunes, the kleemann box tune is right on the money!

As for why the 5th gear pull was stronger then the 4th gear pull, you have to keep in mind, that I flashes these vehicles while they we're strapped on the dyno, meaning minimal time to adapt to the new mapping on the ECU. We obviously ran in on the dyno for a bit, but as the vehicle continues to learn the new tune it will continue to get stronger!

bushburninc63

So a K1 tune for 93 octane is more aggressive and should yield higher gains?

So I've been talking to Cory about sending my ECU into the Colorado Kleemann HQ...do you guys think I'll get similar results (assuming baseline my car is the same) since you have an off-the-shelf program? Or is the program you received different than what they'll have at Kleemann?

Dads C63

CONGRATS Guys,
Those are great looking cars and great numbers. I noticed you already mentioned doing more mods. It never ends!! Have a great time modding and be safe!

James@ACG

You should be very similar.

miami1lt

Thanks, was hoping as much.

Also contacted MB of Honolulu, and they said that a Kleemann ECU reflash will void warranty to anything and everything that could possibly be a result of the reflash (they said that even bolt-ons will void anything closely tied to that component, and it had to be all CAT back or before manifold, which makes sense).

From just a K1 upgrade, what, if any, problems could develop? This assumes I keep it well oiled and take care of it like I normally do--the motor and tranny seem built for more power than it has stock.

miami1lt

Disregard my warranty issues...looks like the burden of proof is on MB per the M-M act discussions in other posts.

Besides, I'm guessing that if I crack a rod or camshaft, it has nothing to do with the upgrade, and more to do with lack of overall maintenance (or an already existing problem). I suppose at that point it is up to the God's of Cars to determine fault.

Hans Delbruck

Great info, great pics........... GREAT POST!

C63newdude

Very good review, very well detailed, people shouldn't have to guess when going for a Kleeman upgrade. I really wish the torque numbers were higher. I don't know what is about this engine that the HP jumps high but the torque remains hardly changed.

Thanks for sharing.

superlubricity

I'd say dead even based on our 5th gear 60-170mph runs.

avengerboater

Roughly even, dead even--all semantics.

Are you still having any studdering?

superlubricity

Nope, smooth as silk now and I beat the hell out of it up and down I-90 today.

avengerboater

NICE!!! So you're gonna keep it as is and not use the BMCs or take out charcoals?

superlubricity

Not sure yet. I'm going to play around with different combos tomorrow.

I'm considering ordering the "Rest of World" airbox lids from James to use with the BMCs.

superlubricity

I'm setting up a second dyno day for end of February (either the 27th or 28th). Please PM me if you are interested in attending. Looks like we'll have at least four C63s and quite a few 55's showing up.

E55AMGGG04

I dynoed 411whp / 456wtq on a dynojet BONE stock. My car is running at full potential. That CLS is def reading a little high.

Overall nice pics and nice results.

superlubricity

Cool. How many pulls did you do and what were the conditions/correction factor/smoothing?

DucatiNut (the CLS-owner) was the second owner. The consensus thinks there may be mods on the car that he is unaware of.

avengerboater

I'd be down for another dyno day!

superlubricity

Cool. I was already couting you as "in."

nrgy and Even Money are also likely in. RLx02 (Kleemann C55) and BeltFedBob (Kleemann SL55 back from the shop!) have expressed interest as well.

I'll reserve Sat the 27th once we have 7 confirmed.

nrgy

Yep, I'm pretty sure I can make either of those days. Thanks for setting up another one!
