ECU Tuning question
Anyone have their car tuned by OE tuning https://oetuning.com? Their website says CLK550 HP gains are 32HP and tq is 27lbs. Thoughts? Is that possible? and at $395??
And for those of you who have had their V8 CLK ECU tuned, will 20+ HP tune increase be noticeable?

My ECU tune was done by Kleeman and I installed their headers at the same time. I could, and still do, notice the 40-50hp gain.
You should notice 20+. Depending on how attuned you are with the car's performance, I think even 10hp is noticeable.
Several members of the forum have gotten OE tunes, or at least talked about it.

Those are pretty standard gains for the 550s, if you're calculating something like a 20% loss. I have no experience with OE Tuning, though (good or bad), but- obviously- would rather you bought my tune.

Not at all. On a turbo car like the 600s or 65s the cats are a huge restriction. We're at about 410-420 HP (crank) with just the ECU and drop-ins. Removing the cats on these cars is probably only 10-15 at the wheel (it feels like more with the sound, though). Honestly, I'd skip it- too many emissions/resale hassles.

The emissions test here are done via the OBD connection. I just went through this years session a couple weeks ago.
Regarding the hp gains; 10-15 at the wheels is significant, considering the loss with these cars is closer to 25% than 20%. So 15hp at the wheels is about 5%
I do agree that if resale value in the larger market is a key criteria, you shouldn't go "a changing" things such as cats, differentials, etc with aftermarket products. Resale is not a big item for me. (I think I may need to change the name of my car from CLK550 to something with my initials in it....

I guess the "hassle" factor depends on where you reside. I've had to go back to the installer twice; once due to a coding error in the ECU and then again after I replaced everything in the exhaust except the 2 feet of pipes between the cats and the center channel (replaced the cats as well because they were blown).

)As far as gains 10-15whp is barely at the 'yeah I notice something' limit. Combine that with 2500$ and emission hassles and yeah....but hey if you're having no issues I just might have to duplicate your setup

I have the Kleeman header kit for the M273. The cats are installed into the first section of the downpipe (before the elbow). The O2 sensors are installed. Next time I'm under the car I'll take a pic.
I do not throw any CEL, nor do I do anything to the setup before emissions inspection. When I had it retuned, it was after changing everything in the exhaust except the headers and downpipes. The car threw a CEL but not for the exhaust but the CPS - it cleared but still kept it logged and therefore the OBD showed "not ready" during the emissions test. I had the tuning checked while having the CPS issue repaired and it was out of whack, so it was retuned.
On my comments on the 10-15hp: First of all, the headers may allow as much as 25hp at the crank when combined with the ECU tune, which is also about 25hp. You're going to lose 25%-28% of those numbers between the crank and the wheels. The Kleeman supplier on this forum can (and I assume will) dump some real data into this conversation.
I'm not pushing any mods. Just put smoked led tails on my car - awaiting 3rd brake led - $400 when done - 0hp gain at the wheels......... "Just the facts Ma'am"

yeah! That would make one think at least twice. I'm at about 77K miles now and had the performance work done at about 25K miles and 2 years of age. When I did it I told myself this would be "my car" for at least 4-5 more years. That was 5.5 years ago.

That engine probably doesn't know what badge is on the rear...... tuning will just get more of what it has to give, without changing pulleys, cam shafts, intake, etc.. If more is what one wants from it.
Unless the next C63 looks like the new S coupe, I'm good for another 3-5 years...
