Does anyone know of a company that sells high quality popwer chips for the slk 320.
I'm looking for about 50 horses, and I understand this is a good place to start.
Any suggestions would be appreciated

It's going to take more than a chip to add 50 HP to the 3.2L V6.

Renntech has a chip. They're one of the only companies whose chip actually produces the gain they claim. You might also want to talk to Vadim or Ben @evosport about "PowerChips" as they've been testing one of their products recently. Other mods might include cams (renntech/MKB, Carlsson or Brabus... all good) Intake... Renntech makes one(but i wouldn't expect much for a gain).

All told you're probably going to spend quite a bit getting 50 horsepower out of minor bolt-ons. You're best bet if you want more power is the Kleemann Kompressor kit. For 8,400 for the kit and another $900 for their higher boost crank pulley you could have as much or more power as a 32...

Then again, you could probably trade your 320 for a 32 for about that as well...

Just my 2c.

Yeah. ALOT more than just a chip.

The last I saw, some company was selling a chip for the 320 that they claimed added around 20hp but they took it off the market because the net gain was actually zero.

I just don't see how any chip is going to increase output by more than about 10hp without switching to super high-octane fuel (i.e. something higher than 94 in the USA).

If you do an exhaust, chip switch out the cam and do the intake you might see 25 at the crank(about 15-17 at the wheels).
