Ok it turned off again, then after about 100 miles it went back on. Then off again and on.
This is starting to drive me crazy. I thought these from ModernPerformance were not suppose to throw codes???? I love the intake, but i kinda think it sucks that we all (for the most part) are getting CELs!

 

Scratch that as well! After 51.4 miles a CEL came on!!!!!!! I went to pepboys and picked up a OBD-II scanner, as suspected it was two codes both stated "Running lean (BANK 1)" !!!!!!

 

You said you had TWO codes...
What was the other DTC??

My CEL turned off today. It's been probably 400 miles since I installed it.

Well, mine came back on after about 40 miles

Mine has not come back after 2 weeks so I'm thinking the PCM is adjusting?

 

Mine turned back off today. Wonder how long this is gonna happen.

Unfortunately you are likely in this for the long haul.
Once the MIL comes ON, the reason it sticks around for a while is the system will require 3 consecutive ign/trip cycles w/o FAIL before the lamp will go out. Then your driving habits may not put you into the affected weighted cells long enough for the maxed out trim value to be recognized as a fail (2 minutes) So once you eventually get these conditions to exist the light will come ON, and the cycle repeats.
