No on has tried the trick flow on here! I'm aware of the ATI one but that's little high priced!

On a motor like that you are CRAZY not to run ATI... Otherwise run stock because it will not make a HP difference anyway. There is a reason most all max effort LS builds run ATI. I realize you are trying to save where you can but don't do it here... Stock or if you are determined to go UD go ATI.

I have a March UDP on my car now but will go back to stock when I go back down there.....
