E70 4.8 Chip tuned
 

I have search all the threads and there doesn't seem to be any real clarification to what the 4.8 can be chipped tuned to..H/P.TQ.. There are some thread that claim that we can get around 400 but I feel that is probably impossible.. If anyone knows where we can buy such a tune I would greatly appreciate it..

No chip is going to give you anything significant over the 350 hp you have, without many more modifications.

YEA Thats what you would think.. I wouldnt mind getting an extra 10 with more precise shift points though..
