my tuned and downpiped E63 pulled hard on my buddies Gpower tuned M5, same out come as out first race but less lengths, he jumped me and i caught up and pulled on him 2 lengths! he was bent, no video cause i wasn't home to install my gopro.. but im sure we will do it again!

my problem is i think the clutchs start slipping after hard driving with these mods

these cars are pretty fast with the mods but I am also feeling that the mods are too much for the stock parts.

My clutch is slipping also and the transmission is getting jerky

are you getting vibration at higher speeds around 75-80 mph

hyperion667

sounds fun, hope you get the issues sorted out

NickE63

Wtf no mine is not vibrating but slips lil when I pull out of driveway in reverse and then lil going forward, I notice that if I put it into park then drive again I feel it engage better, could be all in my head. What are you going to do? I'm bringing mine in

this issue was seen on my car even when i was stock since day 1. specially after reverse/D.

EDIT: only in C mode

nothing wrong with the car.

Nick have you dyno'd your car yet with the full compliment of mods? I was under the impression that the MCT can handle a full boat load of tq...

NickE63

I have an appt to dyno my car tom at 2:30 mustang dyno. Ill get back to you with the results. I'm driving it now no slipeage issues at all wierd man

I drove my cousin tuned CLS63 yesterday and the clutches slips

Did you get your car re-tuned for the downpipes ?

NickE63

Really when do the clutches slip when your getting on it or when taking off please explain. No i haven't retuned it yet for then down pipes. I'm confused some say it adds power some say it doesn't, a few tuners told me all it does is turn of the cel which I never got. So I kind of put it on hold! Any input you can give ?

NickE63

Thanks pal ill try it in sport etc

Faris63

It slip only when taking off from 1st to 2nd I didn't notice on the other gears that crazy on 25K miles car maybe these cars can't hold the power of tune

I'm confused on the downpipes too I didn't ask if I need to re-tune to get more power or boost
I raced my cousin last weekend we were even same result without dowpipes

NickE63

Try what Ali mentioned in sport mode try taking off with that instead of C mode

Faris63

Oh I didn't see Ali post .. it was on C mode

Ali_E55

my car has 60k km on the clock and gear oil + filter was changed @ 45k km.

it rarely does it on C mode if i am reversing and then put it on D, i noticed if i am reversing and the car is still going slowly to the back while hitting D and pressing slightly the pedal, it will charge RPM for a seconed or 2 to RPM 2000 and then the car will start moving, but if i press the pedal a little more it will catch jump directly. ( only in C mode, starts with 2nd gear)

it is like charging the clutchs or untill they hook up.
