Default running too lean

My service engine light came on last night. I checked the codes with my X-CAL2 and it said the system too lean Bank 1 and 2.
About a week and a half ago I installed an accufab plenum and trick flow throttle body.
Is there any way (prefferably inexpensive) to fix this other then a dyno? Any help would be appreciated/
