Custom Tunes fix lean conditon?

[iHellFire]

I have had my Gryphon for about 5 months with the gotts mod. Two days ago I ordered a CAI. I got it today, installed it after returning my truck to stock. I have placed an order today to re-tune the custom calibrations I had set on my gryphon since they were not set up for a CAI. Well I after doing my first test run with the CAI, check engine light came on and I got two lean codes. (171,174) I am seriously worried now. Do I not need to drive my truck until my new custom tunes arrive for the CAI and put my stock intake back on for now?
