I didn't notice any increase in lag after my fmic install, there is more power everywhere, especially after its warmed up where heat soak would normally kick in. I then ported my exhaust manifolds and it spools up 500rpm sooner. I also have an old link plus v10 standalone but the antilag is too crude for street use. I do use the launch control/flat shifting option when someone tailgates me, it blows fireballs of unburned fuel out the exhaust. They usually always quit tailgating after I do that ;-P
