Easy performance upgrade for slk 230?

I read somewhere that replacing a pulley can increase Horsepower on an slk by 10% or so. I don't recall which pulley...
If true, I imagine fuel consumption would suffer to some degree?
Any insights would be appreciated.

IMO, it is not worth it. 10% on a car that weighs over 3000lbs with barely 190hp is just not worth it.
That tiny engine is already getting worked very hard. By changing the pulley you are increasing the boost psi
which can create a lot of problems or even a catastrophic failure.

If you want to go faster then move to a V6 or V8 CLK left original and it will run for many more years.
