I have the LC-1 on my evo, works great. Some people have problems with the sensors going out, but I have had good luck with mine. I bet if you asked nicely you could get it for a great deal from MAP or one of our other vendors.
Oh, and it does have narrowband emulation setup as well...you can even program it to be whatever AFR you want

Default is 14.7 of course.
