    What to change for LT Headers

    When you install LT headers with sim's in the back O2's what tables do you change to get the LTRIMs back into the 0 to -3 range? Do you scale the injectors or one of the other tables?

    Yeah,
    The quick way and safe way for you since you have an automatic is to scale the IFR. You may also need to mess with cranking fuel a little depending on how much you scale the injectors so it doesn't start funny.

    You can also mess around with the MAF and VE tables (talked about elsewhere on this forum) but I don't know how that will affect the transmission (I have a 6-speed).
