Excellent idea. I'll check out Amazon. They sell everything!

With a simple piggyback or ECU tune, what do you think we'll be able to squeeze out of the C450 ? what kind of power is a tuned 400 putting down these days?

iwork4wine

ND,

I have been looking into squeezing out additional torque and HP for the c450. Too bad M-B does not have an agreement with tuners similar to Dinan for BMW and Stasis for Audi.

Currently Renntech can boost the C400 +50 HP (379) and +55 TRQ (409).

I spoke to Kleeman USA and they mentioned they can boost the C450 +60 HP. The web reflects 413 HP and 428 TRQ for the C400.

I will certainly wait until at least the Spring 2016 before I make any decisions. I think I would be pretty happy with 413/428 as long as gas mileage did not suffer too badly.

It seems to be a lot of confusion here. The C450 and C400 are exactly the same engine DELOS 276 there are zero mechanical differences. In fact the difference is an AMG "tune" and a red engine cover. The only available tune for the 276is the Renntech one and is a very good one since as the AMG tune in the 450, its only a slight boost of appx 1psi or so. Im sure the engine can be boosted 100hp quite easily, but you'll end up with a "boost monster" which is constantly opening the waste gate and greatly affecting refinement, not to mention ruining fuel economy. The Renntec boost is not worth the money on the 450 since the AMG tune is only slightly less powerful (12hp). If you
crave more power you should simply bite the bullet and get a C63. The Delos 276 engine is fabulous but its not going to become a turbo v8 without the many negatives associated with way too much boost.
So, to make it clear no tuner is going to make anything different or additional with the 450 engine that can't be done with the 400 since the engine is exactly the same, they only vary in factory tune.
When you drive the 450 you'll find it is more than enough power for non racing applications, few, if any cars you'll meet on the road on a daily basis will be able to show you their tailights aside from new corvettes. You will scare mustang GTs and Z28's all day long.

Fyi, Dinan and Stasis both void warranties. They only cover repairs only when BMW/Audi rejects claims. Dealers may rep these companies in their own peril.

Stasis also went under 2 years ago, right after Audi started to blacklist modded cars and they could not keep up with payments.

I have heard our local MB dealer is quite mod friendly but ymmv.

After all, C450 is poweful enough. Would love to see what the dyno numbers are.

Renntech tunes will not void MB warranty. Given the small differences between the renntech and AmG tune I wouldnt be surprised if they are in fact the same parameters, with mercedes simply underating the 450.

ua6-spec

Be careful . Mercedes have their cars tune to a tee. If anything goes wrong on your motor and if they can in anyway tie it into any aftermarket tweeks you made to the car, you can be sure that they will void any warranty. Im all for more power but just make sure it won't shoot you in the foot down the road.

autopal

With what I've read so far about the C450, I can't imagine why someone would need to be worrying about tuning. Unless you want to tune, just for the sake of tuning. We all know the Germans always underrate their horsepower, and I'm pretty sure the C450 will be a monster from factory. I can't wait to get mine. If you really need more power, then there is the C63

iwork4wine

What I was hoping for is the c63 with 4-matic. I live in the mid-atlantic/northeast area and do not feel like swapping-out snow tires each winter and spring.

It looks like that I will have to be happy with the AMG factory tune since not much torque left in the numbers.

Vipershade

The lack of C63 4MATIC was my main motivation for ordering the C450 also. I would have ordered an AWD C63S in a second. I ended up going back and forth between the C450 and the E63. The E63 was more than I wanted to spend after adding all of the options that I wanted (not to mention that the current interior is looking aged), so I went with the C450.

autopal

Me too, I was hoping for a C63 4matic as well. I live in western Canada, so I have a solid 5 to 6 months of serious winter, but even with 4matic, I still use dedicated winter tires and summer tires, the best of both worlds, I guess. I will never go back to all season tires, they just don't make sense.

iwork4wine

There is a lot of rumors that circulating the M-B will produce a 4-Matic C63 but nothing yet. The hope of a 4-matic C63 in the next 2 years would be the only reason I would lease the vehicle over purchase but I am running out of time.

I am not sure that is in the cards for the C. It is too bad since the S and E classes have produced these vehicles.

c4004matic

I would most definitely buy one. I think the barrier is that the C class 4matic system simply cannot handle the torque. The C63 also uses a different transmission since the 7Gtronicplus cannot handle it either thus making implementation even more complicated. As it is The C63 is effectively "shoehorning" the V8 and transmission in the C body which takes bumping the nose another 3 inches.

Germancar1

I've never understood this, you have to switch from the summer/performance tires anyway, even on a AWD C63 so what is the difference? Unless a C63 S comes with all season tires, which would be a big waste of chassis/engine.

autopal

I agree, even so, all season tires are useless anywhere there is serious winters, regardless of RWD or AWD

iwork4wine

Aotopal, What do you plan on running (or should I say fling) with in the winter? 19" performance tires are not going to be very useful across the border. I have not seen much with the MOE (run flat) tires. I have the same situation but less sever weather in PA.

autopal

I will be ordering my car with the 19" summer tires, and getting a set of 18" blizzaks, with rims, most likely from tirerack.com

c4004matic

Essentially everyone runs regular snow tires. I just have an extra pair of much cheaper but almost identical rims with Michelin X ice. The tires are all the same width 225. For winter service I have a compressor kit.

iwork4wine

I am hoping that their are better options come late Fall. I may have to ditch the MOEs since there is very limited options. The only thing I came across was Pirelli Cinturato P7 All Season that had at best mediocre reviews.

I did not know I would be in the same predicament of swapping-out tires or I would have ordered the C63. My salesman actually talked me out of ordering the C63 since i was debating on purchase or leasing the vehicle. He mentioned you could do either with the C450 but it made no sense to lease a C63 because of the residuals. Figures that I plan on buying C450 after all. Oh well, I am sure that I will be happy with this vehicle once I take it for a spin.

GrampaJohn

I will run on the original equipment this first winter. The winters here go from mild to fierce year to year, but the streets are cleared pretty effectively around me. I'm curious to see how the 4matic will do. If I need snows I'll deal with it next winter.

Hello to everyone. Have been lurking a while and thought I would formally jump in to the MB World forum. Have order placed for C450, black, cranberry red interior, lighting package, panorama sunroof, premium package 2 (Burmester), rearview camera, illuminated star, and hands free access. Dealer has told me it is red (no changes) and will go into production September 2 (hoping the Labor Day weekend doesn't create distractions for the build process ). Delivery in late September or early October. Like others with cars on order, I am trying not to wish away the time waiting to take delivery, but very excited.

rbrylaw

Congrats on your C450 order. It should be fantastic and yes, the wait is painful.

Jeffy

This is correct. ANY engine modifications from any tuner can void your warranty if related damage occurs. Mercedes states that in their warranty and so does MB customer service. MB dealers (which are not part of MB/Daimler) that install tunes are doing so on their own not with MB permission or implied warranty.

Jeffy

The Biturbo V8 550s are another option for step up in power/torque over C450 without the AMG price tag. Its well documented that MB underrates the 402hp/443lb-ft numbers as many dyno runs have shown stock 550s around an average of 440hp/500lb-ft. Not putting down the C450 in anyway just pointing out the 550s are great sleepers at low 4 sec 0-60.

C450 Exhaust - Not bad for a non AMG Mercedes. Definitely beats the 400.! Want to see what Eisenmann or Akrapovic come out with.
