This is how a lot of the GM v8's with HP Tuners did lean cruise before HPT unlocked the lean cruise part of the pcm. It's discused in this thread, http://www.hptuners.com/forum/showthread.php?t=4929

I dont remember who brought up the wanting to cruise at leaner than stoich.

A member on a local forums www.240sxone.com told me about this what do you guys make of it?

most of us running standalones with a wideband are running leaner than 14.7.

I think I tune for 15.5 in cruise. Some go as lean as 16:1.
