Sorry to be a pain but can anyone direct me to a thread about the zf 6 speed auto. More specifically what to do to sstrengthen it. I just joined and I cant find anything about it. I have a 09 fg turbo and I want to push for about 375rwkw. Amassing all the required bits, but before I do anything I want to beef up the drive train. Custom tailshaft, diff bushes, trans cooler, high pressure lines and valves an input shaft ans a tune for the box. But dont know sh*t about the zf. People keep telling me that if you try tune them they go to sh*t. Anyhelp is much appreciated!!! Thanks
