Got GSC S2 cams, 1000cc injectors, E85 and an exedy twin disc in my ‘05 MR. It’s literally impossible to get the car moving if I’m on a steep enough hill. All I get is a lot of chatter. When I was on my base map after getting all the mods on I don’t remember having any problems with drivability but maybe I just didn’t have any hill starts. After I got it dyno tuned that’s when I really noticed that it’s not possible to start moving on a hill. Is it the tune? Does the clutch pedal need to be adjusted? Is it just normal for a twin disc? I’ve even tried giving it a lot of gas and slipping the clutch and still wasn’t able to make it up a steep hill.

 

uhhhhhhh......

sounds like the clutch is just chattering bad.
