Toyota Tundra Forum : “Jet Mass Airflow”

Jet Mass Airflow

Has anyone tried the Jet Mass Airflow upgrade?  I already have an intake a spacer and after market exaust.  I put the Jet on the other day and the check engine light came on.  Now the truck wont go over 3000rpm.  I've pulled the battery and tried to reset the computer.  I have also pulled the spacer out assuming that it was pulling too much air.  Still noting work.  I've even tried switching back to the old sensor but the problem continues.  I have also already replaced all my o2 sensors.  Is there another way to reset the computer or do you think it might be something else?  Thanks for your help!
