While dyno numbers are interesting and good for tuning, they can be easily skewed to look real nice. Will part of this challenge include track times? I'll take a crappy dyno pull and great 1/4 mile run over a great dyno pull and average 1/4. I currently have a LET tune and I'm satisfied. 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.
