| I had already done the 3" downpipes, MS manifolds ect so with these other mods this one was badly needed to get the air in since I am getting it out now. I am blown away with the performance difference going to dual maf and I guarantee it is way more than a 9HP difference. This REALLY woke up the gt600's, Feels like a V8 after 2800-3000 rpm now where before I was disappointed with the lag up to about 4k before.
