I have a used Apex-i S-AFC Blue Version that I used for about a year in a half before I went MSnS. Truthfully, I loved this little fucker, worked for leaning out my huge injectors when needed at different RPM ranges. Paid like $300 new for it. Will take $120 shipped for it and I can ship it Monday for ya. No installation instructions included mainly because I dont have them anymore, but there is a diagram of how to install it on the MODS page directly on this forum!!
EDIT: Sorry for the GIGANTIC ASSSSS picture, if someone wants to resize it, be my guest...
