if it helps, when i dyno'd there last year, my z28 with a 01 LS1 put down 343/347 with just a lid, no muffler and a tune. i thought it was a lil high myself. i was running 12.2's @112mph with skinnies and only the spare and jack removed at the time
i remember my 98 put down 335/353 w/ full bolt ons with a tune at rpm in delaware
only thing im thinking is the truck sucked in some nitrous thru that custom CAI
