I recently got a CLS550 and love it so far but wanting a little more power, wheels and lowering are in the works for this month as well as the resonator delete I just read about. But what other options are there to crank a little more power out of this thing without voiding the warranty. Or a fairly easy switch back to stock.

ECU tune is the most bang for your $$..

are you talking about the Ren tech one for $3100?

I think its listed at $2,740.. they claim 530hp 600tq.. So yea, for the $/gain its worth it. Other vendors sell cheaper tunes also

You can also get Kleemann or Eurocharged for much less.

Last week finally did the resonator delete and sounds great, lots of compliments, a local shop also told me to do K&N but also wondered if there was an intake setup to get rid of the plastic intake pieces. Going hold off on the tune right now, want to lower it, put wheels on it and small mods. Just got married, bought a new house etc so can't go to crazy right now.
