Hey all- seen lots of good deals to remap to gain 20bhp and improve mpg - but... Is it worth it? Has anyone done this? Does it put more strain on components? I have heard a remap can improve the wellbeing and running of your car.

Advice is welcomed! (not that it's not quick enough already!)

Thanks

No its not worth it... My previous was a 05 CLK55 Cab, I remapped it, de-catted it and panel filtered it.... It sounded awesome with the decat hence everyone doing it, but the normally aspirated 55 lump is the best its gonna get as is!!
I still miss it....
What you already have is a missile.. so de-cat it to release the V8 and leave the rest alone....

Like Baldguy says, for what the cost implications are, you will never get a noticeable gain from a normally aspirated V8.

I don't think you'd feel 20bhp more in a 380+ car, either.

Its German, has a round badge, reminds me of a Mercedes. Satan fuelled
I had mine (SLK55, not the troll mobile) remapped by DMS.

It gave it a noticable mid range shove.

It also removed the limiter. needed for a few runs down some runway somewhere.

You can always have it put back to standard if you don't like it.

Tell the insurers.

I would personally remap it along side something like headers,

which is why i've bought these headers;:D

I'm fitting the headers and having my ECU remaped, hoping to hit the 400+ mark!;)

Thanks for all the ideas- where do you suggest I remove cat- do I need to source a cat replacement pipe? And how much £££

The ones I bought are simple bolt on's and should give around 18-21bhp, (based on people's results) plus ECU remap should give you around 20-25bhp, it will all add up!

you be looking at £700 plus P&P

around £800 and they claim to hit 400bhp which is total rubbish!

Seriously? 700 quid for a cat replacement pipe? Where would you purchase from? I remember de-catting my evo6 for about 100 quid!

As the pipe is for a Mercedes they probably think of a number double it and add a little more.

Maybe he is talking about the cost of the headers?

Benzedup is referring to the manifolds ("headers") costing £700. Allow half that for good quality cat replacements on an AMG.

Also, remember there are two pipes on a V8 compared to one on an I4 engine, so double the cost for that, and consider the length of replacement pipework.
