I have a line one a 6.4 setup...maybe i'll keep it simple, sump to 6.4 to stock 6.0 see how things look...I'm no where near 600, seeing other similar setups i think i'm 500ish. but that's just guessing.
FP isn't dropping below 65 at wot now, but I'm thinking of adding some insurance to keep from having to spend big $$ later. hence the post here. I really appreciate all the input guys.
Building my own setup isn't out of the ? but i can't bring myself to completely throw out what working now the more I think about it. If it dies it's a completely different story.
