What Happened

well i install my new LPE LS6 intake. the install went ok, other then having to get a new oil pressure switch. My mods are LT, Lid, cutout, LS1 edit. well my first dyno run with tuning on old LS1 intake i got 315rwhp and 322rwtq, now with the new intake and after tuning i got 304/311. what the heck happend here and why. my a/f is 12.9 and timing is 29. i went as rich as 12.3 and lean as 13.2 with timing running from 27 to 29. even with the cutout open i only got 2 extra hp up top but lost 5 hp across the rpm band. only thing i c that has changed is the outside air temp. now it is 82 and 99% humity today. when i got my car first dynoed it was 73 and 30%. could that effect it that much. also this is on the same dyno. any info would be great thanks

My guess.. different weather. Dyno's correction factor can be affected by weather.

"could that effect it that much."

Yes, especially if those weren't corrected numbers.
