Yeah it is def not 10k more lol and where are you guys getting minor increases in power? Both the E43 and E63 are biturbo and gain 100hp with a tune, so I do not know where you guys are getting your info from haha. I don't see triple digit hp gains as "minor"

c400
just saying if there is a C400 w 500 hp.then just wait and for what the e43 has shortly, I was hoping of E43 coupe news, but I did go to my MB dealership and tell him about my tune, he said no prob and that is the biggest MB dealer period..., for thoses who live in socal you know, but if a c400 can be as fast as the c63 then wait for the US turbo upgrade, I know the e43 has a bigger turbocharger and maybe it can be retrofitted ??? WONT BE LONG TILL YOU SEE A E400 COUPE BEST A E43 0 TO 60 ,Anyway check out the link I think the for now a good tune and exhaust is the key. I THINK E63 is just a different class but for 120k lot of options jmo

I'm liking the oe tuning option http://www.oetuning.com/products/mer...s-benz-e43-amg

With the year end sale, the $/hp is very competitive.

Obviously the price is appealing because that is the only way to distract people from the fact that AMR's tune is better lol 100 more whp and a motor warranty? I rather pay the extra for a higher power/warrantied tune. No offense to you guys, but you get what you pay for

Just had my wife’s 2018 E43 tuned by dealer (TampaBay) they use Kleeman I think and doesn’t void warranty. I also did catless down pipes. It sounds fantastic. At cruising same as stock. When you put your foot in it quite bit louder about same time and now idea what the other poster is taking about. It’s not overly raspy and tone didn’t really change. Just louder under throttle and sounds great. Taking off stock mufflers and resonators is stupid and will drone every time.

overall quite happy with the combo. It feels lot faster but on top end not as dramatic a change as when had my SL 63 tuned. Good amount more torque but the HP isn’t as big a deal. Overall though it rips 0-60 now. Would bet it’s in high 3 second range.

Personally I would leave it alone given that its "tuned" already. The engine its rated for 329 hp. The other 67 are the "tune" which includes upgraded turbos.
r u stupid the tune is for 329 moreso than 389. It’s UNDERTUNED to 329. Mindblowing right.

Before you imply that someone else here is stupid, which is not cool, you may want to verify your own understanding.

From what I understand, the M276 DE 30 LA variants' power increases were not achieved by software tuning alone.

The 329hp variant was released first, so it's not de-tuned from anything.

The 362hp variant has a lower compression ratio and increased boost from the 329hp variant.

The 396hp(US)/401hp(EU) variant has larger capacity turbos and increased boost from the 362hp variant.

There may be more differences between the variants I'm not aware of also, but since this thread is about the E43, they all had the same engine specs (2017-2018 396hp/401hp).

Hello good afternoon,
I was once told that the engine from the c43 to the e43 had different internals. As well as the pistons that would be forged. But I'm not sure.

when it says catless downpipe, is it removing the inside? Or did you install a new downpipe?
I have the same problem, at low speed there is no noise. It looks like a normal version like the c200.
