    • AMR Performance W205 C450 (C43) revised Stage 1 tune gets 371 rwhp from the M276 DELA30 turbo V6 and runs 12.3@112 in the 1/4 mile

      This is incredible considering that AMR Performance already showed a gain of 63 horsepower and 100 lb-ft of torque at the wheels on the 2016 W205 C450 model. That was with their 1.01c tune revision and now with their 1.02b tune revision they take things considerably further.


      How about 371 at the wheels or in other words another 53 whp from where they already were? That is more than 100 horsepower at the wheels over stock:


      Utilizing this tune and no other modifications a C450 went 12.3 @ 112 in the 1/4 mile in 98 degree weather. We expect easy 11's in winter conditions or just cooler weather:




      We are waiting on the slip but AMR is pushing the C450/C43 models harder than anyone else along with the M276 DEL30 engine.

        Great gains. Is this all on pump gas?

        Wow that's really impressive. I guess the '43 series aren't that much of a joke with this tune...

        Just checked the SLC43 pricing here, ~70,000 base. Nevermind that option, back to a used C450 or C43.

        From what I understand, 93.

        Impressive! But the baseline is quite a bit lower than I expected. 265 WHP from an advertised 365 crank motor? Even at 20% drive train loss that doesn't compute. Also I would assume the car came under rated from the factory.

        Regardless, the tuned numbers are great.

        I only have 2 questions at this point:
        How do we get this performance while keeping the MB warranty?
        Do I buy a AMG C450 today, or wait for the AMG C43 with the new 9 speed transmission?

        I joined this site because of the rumors the C63 would get the 5.5L TT, DCT, and AWD.
        AMG did NOT deliver.

        But, a sub-4,000lb AWD luxury sedan that runs 12s for around $50k will make an excellent daily driver, as long as the warranty stays intact.
        I refuse to drive a German car out of warranty.

        Although I'm scared $hitless to own a German car due to reliability/costs, I think I'm in.

        You don't if you're driving a C450. You can not expect to tune and retain the warranty.

        This site told you repeatedly that was not going to happen and to stop dreaming about it.

        Any intelligent response on buying a C450 or waiting for the C43?

        Hate to tell you this but tuning any car from any manufacturer and trying to get a warranty claim to go through is going to create problems.

        Same engine all they did was kill off the C450 Sport. The best choice is the one that is the best deal.

        C450 VS. C43
        -9 speed VS. 7 Speed
        -New AWD tuning/split
        -Unknown additional changes


        I've never had a major failure on my Corvettes that were all tuned, and never had an issue with the dealer honoring the warranty on my tuned Corvettes.

        Regardless, since MB refuses to offer AWD on the C63, I think they should allow some sort of tuning solution with warranty, that fills the void the lack of a AWD C63 has created.

        That was a long time ago but if you feel that way buy a Corvette I guess.

        The C43 is the closest thing to what you want or buy the new E63 when it comes out.

        WTF? You know NOTHING about me, my cars, and my history. Let alone how long ago my last warranty service was.
        As much as you want to pretend, you can't deny the cars that I own/owned, and that I've built over the last 3 decades.
        Yes, it was a long time ago since I build my first 9 second car in the early 1990s.
        But, I've been buying new Corvettes since 1997.

        For the record, I REFUSE to buy a C7 because GM only authorized $250M of the $900M that was requested for the redesign.
        Since GM did not fully invest, neither will I, because the C7 is not a worthy upgrade over my C6's.
        Offering a torque converter instead of a DCT in a modern "all new" sports car is pathetic.

        Which reminds me, I was QUOTING actual PRINTED lies from Corvette ENGINEERS regarding the A8 transmission, when you trolled me as if they were MY words.
        They were NOT.
        Corvette engineers are documented liars who are full of $hit, not me.
        You banned me at the time with bogus negative rep, so I couldn't even respond.

        Ok, buy another one then but this isn't the 90's GM any longer and expecting anyone to cover your tuning with a factory warranty borders on insane.

        You were wrong. No big deal.

        Anyway, does this need to be a discussion about Corvettes?

        Back on topic please.

        How F can I be wrong when I quoted Corvette engineers to prove they are full of $hit? LMFAO

        Any edcuated car guy knows that custom tuning done by an EXPERT, preferably on a dyno, just optimizes a factory tune for increased MPG and efficiency, not just more power. Factory tunes are WAY off due to the wide variances between end user's altitudes, octane, etc etc.

        Since MB does not offer a AWD C63, I just think they should support some sort of warranty supported tuning to bridge the gap between the AWD C43 and C63 performance.

        I really don't think rehashing this is necessary in this thread.

        I agree but you need to tell that to the people who set the warranty claim rules at every manufacturer.

        They'll tell you that's the C43.

        Is AMR going to update the c400 tune also? Same engine but they post different gains for the 400 and 450 on their initial tune.

        That's a good question. I'll see if I can find out.

        Now that you can get a 43 AMG trim for almost everything I'm wondering if there have been any more updates. I saw this on their site, almost 410 AWP in the C43 platform:
