Much more responsive. Pulls harder off the line and up high when I get in it on the highway. It's not a killer combination, nor did I expect it to be. But the new numbers are much more in line with what I wanted in a street cruiser. The 3.55s with the OD are awesome too. Decent bottom end, but I can keep up with 75mph hwy traffic turning like 2500 RPMs. I know the 518 eats some power, but it's worth the streetability to me.
The EFI is still learning a bit. If it hit it too hard from idle it still has a wee bit of stumbled, but not like a carb. The more I drive it the more it learns.
