    Can i install the 2.5 bar OS on a NA truck...

    Unitl my turbo shows up next week. And ive searched until im blue in the face, but can any tell me a good place to start once i load the tune and have my turbo on. Whats the first things i should address as far as dialing in the tune. and as far as the first part of the question goes, will it hurt to load it up while my truck is NA? will i have any issues? i already have a 2 bar map sensor.

    Yes, you'll just need to put in a base tune but it'll work fine, we have many customers running maf & a 1 bar map sensor using the E38 2.5 bar custom operating system since all the axes are fully adjustable.
    It doesn't have to be perfect, it just needs to be done in two weeks...

    Once you start getting into boost, you just tune the new areas of the SD table.
