Not quite bro. The uppers come in 2.93 (stock), 2.8 (1.5-2 psi over) and 2.75 (2-3 psi over). No such thing as a 4,6 or 8 lb upper. You're dead nuts on about the lowers tho.
And it looks like the same pulley as me, a 2.8 upper. With the CAI and that, with a tune, he's looking max 380-390 at the wheels, and that's asuming he's got a lower to go with the upper that's on there. If there's no lower pully, drop about 10-20 hp off.
Good races tho. It looks like it would've been a better race if you guys had gone further.
