Hello everybody,

I have a question, if ECU tune for my W209 CLK55 is worth it?
I can get a special price and is really a great deal.
They claim to get 390hp comparing to original 367hp and 592NM comparing to stock 510NM(that is 437lbf·ft comparing to 376lbf·ft stock).

I am very skeptical about the numbers. What do you guys think? Worth it on an N/A engine, or better not do it?

My only "peformance" upgrade is quad exhaust with secondary cat delete and muffler delete, replaced with magnaflow resonated x-pipe in the place of 2nd cats. So far the car is stock.

 

it will benefit you a lot car will be night and day look at clk550 they get a tune and walk stock by about 2-3 cars.

 

The torque is kinda high. Who's tune is that? I really think a tune is worth it even on a na motor. I'm getting one from Eurocharged and i'll know soon!

If you already have the exhaust work done then that would be the next step. good luck!

 

Do it man...you will be surprised and may i asked where are you going to do it ?

 

torque seems way high.....

 

Does the EC tune improve the trans shifting also? Dyno #s? Based on what Ive read here the C55 guys seem pretty happy with your tune.

-Thanks

 

I wouldnt hesitate and the numbers sound about right.
Im getting mine done by Powerchip France and they claim +24hp and 92Nm of torque!

 

Thanks everybody for your replies. The torque seems high to me as well. But maybe im gonna give it a try.
Sorry guys, not in US, they are situated in Czech republic
Thats like two hour drive from my city in Slovakia. Their reputation is quite good in our area and they have 50% off this month.

I wasn't sure if a tune on N/A car is worth it, but relating to your replies i guess i will do it.

 

are headers with no cats legal in you country? If so I would put headers on first and then tune it

 

We call no cats a test pipe or off road use only thing up here in the northern part of the US - my '93 mustang is situated as such - we do not have inspections up here.

 

i had my car(ECU) tuned last week by eurocharged,put it several times on Dyno,race it with 4 clks 55,the result is amazing (2-3 cars diff) especialy from 5500 to 6700 rpm!!! i have 20 years experience in tuning BMW & MERC,this experience says that no one gave us the TIME & RESULTS that jerry gave & give us everyday.....

 

yes it does!

awesome!

good to hear! We feel like we have one of the best products in the buisness!

 

Arghhhh, i hope that i was in US, so i can get a tune from Jerry. Heard only the best about him

 

we remote tune all over the world on a daily basis!

 

I am thinking of getting headers with highflow primaries, since i don't have secondaries anymore.
Should i go better with short tube or long tube headers? I don't plan any forced induction in the future with this car.

 

Oh really? Can you PM me pls some more info and pricing? I should really consider this option.

Thanks

 

All I have 2 say is I love my tune

 

I would also like the same info when you get a chance.

 

can u do a remote tune on my w210 E55 ? same as all these guys gettin done on their newer cars ..
also would you happen to know of any numbers differnce ..thanks

 

Dear Michal,

I Have also CLK 55 2003 model,I took it to dyno test when she was stock she gave me 380hp,i could claim it again to reach 396hp with 435ft-lbs.
But The thing is that everything still original,resonator not delete it,but the filers are K&N and the car is full serviced with a very excellent condition ! I've raced with the same car that has my same file and still i moved her 2-3 cars!
N.B : I've raced with 2 cars that has eurocharged tuned,one of them is clk55 and the 2nd is C32 and both of them i ate them :P

 

PMs sent

 

Dont u have any pic for ur dyno result ?
What do u exactly wanna know ?

 

A tune is tempting...

is it a problem if I have Sprint Booster?
Is it a better tune If I have no resonator and changed for high flow cats...

Do the tuner needs to know this info before the tune?

 

A) Sprint Booster is fine with ECU tune
B) Delete all that crap
C) It won't hurt

 

I'm also looking a a ECU tune on my 2003 clk55. Has anyone use jet chips???
