Guys a have a stage 3 3 door cosworth with a MSD chip in a L6 ecu

I am interested in anti lag but don't know what I would need exactly so far I know I need a L8 and a chip from MSD but that's all I know

I have messaged Stu @ MSD but had no reply yet

I don't want to see people's opinions on me not needing it as its illegal etc I just like the sounds simple lol
