I checked the pcv lines under the intake and all is good. I have a grimm speed manual boost control solenoid and a mishimoto catch can. I dont know if its that causing the leak or what. Any input would help! Thanks!

P0171 lean code.
possible exhaust leak near or before 02 sensor, cracked header
P0441 evap purge issue.
check evap purge solenoid if you have repurposed or removed evap purge solenoid you would need to disable that code, if not evap purge solenoid possible faulty or vacuum/boost leak leak
