Hey Larry, no i didn't take it to express, i handled it through Diablo sport. talked with a tech for a looooooong time and we finally adjusted the air ratio right so no more lean codes and my truck runs gr8. Thank you again for taking a look at it for me, i appreciate it.
did you get a custom tune for that intake or did you get an over the counter diablo?
I have always had my programmer custom tuned. for the intake. Intakes chenge things a lot. like position of the Mass meter. And tube size.
Have you looked to see if there is leak. were you careful when you swapped out the AMM. is this the first time to run the diablo could the problem be prexisting. you should have run the codes before you installed the tune from the diablo.
did you drive your truck with the CAI before you installed the diable?
did you erase the codes and did they come back?
I would look for you. if you want to come by.
