I just picked up a FI 476/87/1.0 paired with 150%'s and dual pumps, on a 1800uS tune it hits pretty hard starting at 2100-2200 rpm.
Even with my truck currently being a 5.9 6 speed, if I shift at 4300-4500, I experience about a second to be back on full boost.
Looking to load a 2200uS tune soon to see if it'll come up a tad quicker.
