I just installed the NW dual intakes and about to install a wideband before I install my NW mani's because I might start running lean up top. I say all that to ask if there are any issues with tuning the fuel with those mods and a 185 pulley? I remember 240 having problems with leaning out with similar mods and the 185.
A very good question!

The reason for my pervious question was to see if a leaning condition was evident starting at around 5k rpm. I suspected the answer was no, since my relatively minuet sampling has not reviled that condition with those running a 178 or SC pulley. Speaking solely from what I have seen, there is a top end leaning condition with the 181 and 185. IMO, it has less to do with the tune and more to do with the fuel delivery system.


Speculating......
