    MAFless LS2 (2005 GTO)

    I have decided to go MAFless and try the 2bar speed density tuning (11lbs boost). My understanding is that I need to purchase a 2bar MAP sensor and IAT sensor. I have HPTuners and will upgrade it to 2bar. I did a search and wasn't able to find anything. Is there a 'how to' written up for this conversion? Does anyone know where I can get the 2bar MAP sensor and other related parts, such as the IAT sensor? I've seen threads referencing the fact that somewhere on this forum is the sensor information, but a quick search didn't find it.

    Thank you!

    Do a search here on "AC Delco" and "MAP sensor".

    Heres the How To:
    Install 2 bar MAP sensor (you can keep the original MAF in place if you are using a blow through system. If it's not blow through, just get a sensor for a 98 F-body LS1 and put it on the "hot side" of the blower (outlet).

    Then read this.
