Default P0456 - NOT gas cap related

Team,

Brand new 40th started throwing a P0456 (evap emissions system - small leak) after 1300 miles. This was not a gas cap issue. Had it cleared, came on again at 1800 miles.

Brought it in today, they checked hoses/clamps/valves/cap, did a smoke test, nothing was found.

Thoughts/recommendations? I am planning on installing intake/CBE/HFCs soon, worth trying to resolve this beforehand? Is a small leak ever associated with the exhaust system... so is it possible the new mods would actually address the issue for me?
