    Mafless tune custom OS vs not using one

    Hi,

    I am tuning my vehicle to run mafless. Right now i have the VE table dialed in and setup and running pretty good. What I am wondering now is, is it worth it to install a 1 bar custom OS tune? What are the benefits from going to this OS? What are the downfalls? Is it worth the extra credits to purchase it? Will I have to completely retune the VE table if I install it?

    I am running a 2004 LS1 GTO 6spd, Headers, Intake, Catback are the only mods currently?

    Thanks

    No advantage for you. Helps during tuning process and if you have an older o/s with secondary ve table.
