    If you installed it yourself did you take it to the dealer to get the ecu re-flashed ?

    Take it to a local parts retailer and have them scan the truck and print out the codes for you.

    cant adjust or tune the stock ECU. when installed u get the dealer to upload a new calibration file. only way to tune these trucks is if u go aftermarket and it shouldnt be necessary with the stock S/C kit with calibration file

    Check your PCV valve. I missed that when I installed my S/C and it lead to misfires and a lean code when it was running. It started running so bad I ended up having it towed the five miles to the dealer where they discovered it during the reflash. If you look in the directions I don't believe it mentions that you need to re-attach it and it is easy to forget when you are reconnecting the 1/2 dozen or so hoses to the S/C and air cleaner assembly.
