Hi everyone. Just had the Mopar Lsd, 3.06 gears, rear-end upgrade installed on my R/T w/ R/T pack. I think I may have have my expectations to high, cuz I feel only a slight difference, even with the 93 CAI Predator tune. Do the new gears need a break-in time before I will notice a real difference, or is that just wishful thinking. Also, I have the old rear-end if anyone wants it for free. Thanks in advance.
