My 03 F7 bogs out of the hole and doesnt seem to rev out all of the way like only 7500rpm. Its mostly like this where I have lots of traction, on ice or loose snow its not bad but still not that great. There is a black magic clutch kit in it with black purple primary spring and black red secondary spring. The secondary spring is set on the highest setting too. I just put in a pin and bushing kit in it about 50 miles ago. I was wondering if my secondary spring could be just bagged out or I dunno?? Does anyone have any other suggestions?? Im stumped!!
