I can't say for sure but I've heard 9-10# like LX5liter said. MM&FF dynoed an '02 4.6 w/ cat-back exhaust (baseline was 247hp/292tq) and 6,9,11, & 15# from a KB (latter 3 were intercooled and had a chip) as well as 36# injectors, boost-a-pump from the KB kit. There was a peak hp/tq of 351/366, 399/427, 430/466 (w/90mm MAF, 75mm TB, boost pipe +6hp at 6, +19 at 9, +26 at 11). Those mods plus race gas at 15# was 504/521. I wouldn't risk going above 9# but they showed what it's capable of. I'm liking the 4.6 more and more.
