The 1998 and 1999 C43 has a gated shifter that you can shift between 1-5 gear. The time from when you select a gear to when it shifts is LONG. The shifting also seems to be correlated to the throttle input and by that I mean if you are at full throttle and shift at 4000 RPM the car will hold to redline. The 7 speed will actually shift even at full throttle, I learned this the hard way when playing around with the CTS-V.

I LOVE the W204 C63 and I even commented to my wife how much of a beast it must be once it gets tuned to the full 504 HP. I can only imagine how insane my E63 would be if it was 500 lbs lighter.

The engine sound is unreal but it is muted in the cabin. I plan on getting the MBH headers

What year is the e63?

Beware of the head bolt issue on 07-2011 6.2 V8s

eFifty5AMG

Head bolts are already replaced

503C43 ////AMG

Indeed they were replaced with the updated head bolts provided by MB. It was one of the main reasons I flew out to Philly to pick up the car when I was looking at one 600 miles closer.

UPDATE:

Just got my MyGenius handheld programmer from Eurocharged and have sent in my stock file for a tune. It took all of 5 minutes to download my stock file. I wish it was this easy when I got my C43 tuned by Eurocharged...

I will update in 24-48 hours when my tune arrives

503C43 ////AMG

In standard Eurocharge fashion I received my tune in less than 24 hours (Eurocharged FTMFW!). It takes less than 10 minutes to upload the tune with the MyGenius hand held. I can't believe what a difference the tune makes! Not only is the throttle more responsive, there is more power in the lower RPM's. 3rd or 4th gear @ 4k RPM is INSANE. I truly believe I can easily walk my C43 at WOT going 70 MPH with only 33% throttle input. At this point the only reason I'm getting headers is for sound, I do not need more power.

below is my plan for mods:
Eurocharged tune (done)
ROW air boxes
UPD intake spacer kit (on the fence with this one)
MBH headers

Should be making 550+ HP with the mods listed above

Sound like some serious mods. That's a real beast now

PJmak

Eurocharged tune for a c55 is only $299 now. I am so tempted

DRBC43AMG

Very interesting ROI and hp per $

503C43 ////AMG

do it, you won't be sorry

503C43 ////AMG

ROW air boxes have been ordered with AFE Pro Dry S filters (same filters I'm running in my C43). I think I'm going to pass on the UPD spacer kit. From what I have read the engine cover sits at an angle which turns me off. MBH headers will be purchased around May when I get my annual bonus. I'm planning on getting the full kit which includes long tube headers, mid section, x pipe,and high flow cats.

Sorry for posting all this in the W202 section but the W211 E63 section is dead. There isn't nearly as much activity as there is here.

Those MBH headers will be glorious. All their stuff appears to be King of the ring. You’re shooting for 550 crank, correct? I also have a set of aFe filters on the way for the 55. I opened up my current airbox to find K&Ns..what an oily nightmare.

503C43 ////AMG

I would expect to be above 550 HP at the crank. The Eurocharged tune claims 540HP/495TQ and my butt dyno tells me it is close to that. The ROW air boxes are supposed to be another 10 HP and the MBH headers are supposed to be 50+ HP. Everything said and done I think I would be in the 570+ range.

I have never run K&N specifically for the fact they require oil. Oil + MAF = CEL

eFifty5AMG

Awesome! That’ll definitely be hauling! I’ve loved my aFe filters also because of the no oil, but unfortunately on my C43, the filter seal started to open in the airbox. You can see a little unfiltered gap.

503C43 ////AMG

Just got confirmation MOD #2 is on the way. I have a set of ROW air boxes with AFE Pro Dry S air filters on the way

cm60k

That's great..,,

is there any kind of good pulley kit for your "M156"..?

-;ZAYED;-

503C43 ////AMG

Agency Power makes a kit but I'm not sure I'm going to get it.

eFifty5AMG

Get your aFes? Mine just arrived

503C43 ////AMG

air boxes and AFE filters are supposed to arrive on Monday

503C43 ////AMG

ROW air boxes with AFE pro dry S air filters have arrived

503C43 ////AMG

I installed the air boxes and air filters today. I don't really notice more power but it seems smoother at low speeds and the throttle response is increased. I also noticed more burbles when down shifting. This motor is AMAZING! Someone needs to figure out how to drop an M156 in a C43

mickey13

ive always wanted a c63


maybe,,, just maybe hehe
