I'm running my Sir2 B16 swap at 25psi and it's still smoking a hell of a lot. It's black smoke, and the compression is good all the way around. What do you guys think the problem might be, I seriously don't want to run my car on a lower, I'm just guessing it's the Basemap I Have. Anyone out here have a good basemap for a b16 w/ headers, intake, and exhaust? Thanks guys!

 

have you tried a wideband to actually read your a/f ratios? one persons basemap isnt going to necessarily solve your problems. all blocks are different.
