Hey anyone have tried this on their C63 yet lol? I read about it saying its adjustable somewhere on the engine with a screw. Our cars idle pretty quietly even with resonator, cats all deleted mainly cuz it idles at 600rpm?

Anyone tried raising their Idle RPM to 1000?

Okay nvm not possible on modern day vehicles LOL..

not possible with a screw, the sds can change it alittle say maybe +/-150rpm. why bother though?

Create a vacuum leak and you will have higher idle RPMs

Drill a hole in your throttle plates. That is how a lot of guys adjust for a bigger cam. Don't muck it up or you will be buying a new throttle body and very hard to reverse.

Best bet is to just leave it well enough alone.

Would have thought the tuning guys could do this easy enough with one of their custom tunes??

wow if you know anyone that has actually done that, just keep them away from any car you care about.
