I dont get it 
Does it include ARP head studs? |
S/C, headers, CAI, exhaust, tune, fuel management changes,
should net you about +185rwhp or so. Engine maybe 200hp or so.
426 + 200 = 626hp
Assuming 90% efficiency, you would get 563rwhp or so which is very close to the 562 originally reported.
The numbers above are just my guess, and would need to be dyno'ed to confirm.
