2012 CL63AMG

Why?
Currently when i select "C" Mode in my CL 55 AMG, throttle response is totally different and i need almost 1/2 pedal way to start getting into motion from a stand-still at all.
And this is even described in my manual that came with the car that way.
I thought that this would be the same on the E55K aswell.
So there is already a communication that tells the ECU that i selected "C" mode and therefor Throttle-response/throttle-way is immediately altered.

04 E55
I have been running one of these fixed uppers from shardul for about 1,500 miles now and it is a 180 equivalent on my 04 E55. I have a EC H/E and johnson pump with secondary cat delete. stock crank pulley, stock manifolds. I am still running the first tune i got when i installed the pulley. The car runs great! put down 480.2 whp and 557.1 wtq on a dynojet. Which i was real impressed with and the a/f's were safe. It does pull hard. A noticeble difference from my old 180 crank pulley. i would note the supercharger is kinda noisy at idle.. but just off idle the noise is gone. Part throttle is alot more aggressive now and took some time to get used to but not as bad in "c" mode. the 1-2 shift can be jerky if your not careful. But this car is making boost at lower rpms now. Before the clutch was not engaged. they are working on new tune for me now to help out with this. but its really not to bad. I still drive my car regularly. install was easy, you do have to install a resistor into the harness side of the supercharger magnet connector. i soldered some pins i had on the end of the resistor that shardul provided and so far so good.I personally like this set up better than old my crank pulley. i just wish i dyno'd my car before to see the difference.

In the meanwhile any videos , graphs or anything ?
The thing is the veterans post solid data (I don't understand any of it) but then members like PAcougar, Urbanworm, E55AMGrocket, Sirboostalot etc all of them come and decrypt it and then I understand it lol that's what I was waiting for

04 E55
its a rattle type noise only at idle. you can't hear it in the car, but you can if standing outside.. and it goes away just off idle. i think this be normal when running this fixed pulley. but it could be just my car as i have not heard anyones else's who is running this set up.. i have had no problems in 1,500 miles tho. and the resistor basically tells the M.E. that the supercharger is engaged by simulating the resistance of the magnet.. hope this helps..
