Is this a single or multiple problem cause issue?; I have all five codes at once.
Save the K&N box, its stock. I read the codes with Evolution CS, no programming changes. My complaints are
1. poor MPG
2. intermittent long cranks to start.

P0402 EGR Exhaust gas recirculation flow excessive detected EGR valve, sensor failure
P0404 EGR Exhaust gas recirculation control circuit range/performance Difference between command and actual exceeds a specified limit
P0405 EGR Exhaust gas recirculation sensor A circuit low Voltage below a specified range
P132B Turbocharger/Supercharger Boost Control A Performance
P2614 CMP Camshaft position output circuit Incorrect CMP signal.
