Had the tune performed today. All set expect for the resonator delete which is being performed tonight

Dyno-Comp custom ECU upgrade - Stage 3 Power Upgrade
BMC Air Filters
HKS Spark Plugs

Stock pull only with plugs & air filters installed was right around 500HP WHP & 530 WTQ

With ECU tune car pulled around 620hp whp and around 750tq

620 WHP at approx. 18% powertrain loss (620 x 1.21) = 732 FWHP
750 WTQ at approx. 18% powertrain loss (620 x 1.21) = 885 FWTQ


Not too shabby!

I remember this day about 2 months ago and it feels so good to put down some solid numbers in the CLS63 after the upgrades are installed. Cheers my friend and congrats on the beast in its purist form. Be careful on the roads though.... I have a 2014 and still broke traction in the AWD so I can only imagine what you are going to do with the RWD.

HKS Spark Plugs
Tune is doing great! I added downpipes recently which really woke up the car. Sound & performance. Car pulled 648 WHP after the downpipe install & re-tune

I see people either going with the NGK 95706's or the HKS plugs?

What is the part number on the plugs and they this over the NGK?

Thank you SO MUCH!

rney

Couldn't tell ya the part # of my plugs. I just went with what the MB
Tuner suggested.

X 1.18, right? 620 x 1.21 comes out 750, not 732.
