Ok now Im waiting on my rods that are back ordered till what I was told is next week. Then Im going to rebuild and break in then install this a week later (around 500 miles) Questions are I know that the black box is a hit or miss thing, so I ordered a missing link. Also I was thinking I heard that the FPR was kind of a joke... Should I upgrade this right away? Lets just ask this? If you guys were me, what would you upgrade now instead of waiting, and I dont mean send it back and get a 20g, I mean like with the fuel system and stuff. I know downpipe is a "bitch", Is there an alternative too this? I dont really care to put things on now and then want to replace them in a month anyways.... Know what I mean?
