I'd run the numbers through a ratio calculator before saying it's "not worth it." 4.56 is incredibly short.YES, they do, but the 10% difference is hardly worth it. Looks like i will go with the 4.56 Yukon set up. This lught to get her off the line with more oomph and into the power band more quickly.
I agree. 4.09 sounds good to me and 10% is prob what I’m look for. I didn’t know FP offered them.I'd run the numbers through a ratio calculator before saying it's "not worth it." 4.56 is incredibly short.
