Update.
I received my new converter and have installed it.After ATI got my build sheet they thought a 5400 stall would be better so thats what they shot for.Well guess what , it stalls to 5400 on the T brake. I did a little hole shot in front of my house and my neighbor said he saw 2 feet of air under the front tires.lol I'm gonna hit the track this weekend and see what it will do but it feels alot stronger than my 360 did and it ran 10.30s. Can't wait to hit the track. I will keep ya posted.
