4x2 cal in a 4x4

[bmd2_colo]

Hey guys, hows it goin.

Thinking about converting my Tahoe to flexfuel, have all the flex injectors, regulator, composition sensor, etc.

Question is... Holden has a 512k flexfuel cal for my 0411, but it is 4x2 and not 4x4 (which my Tahoe is). I'm thinking no big deal??

Thanks for an help.

I'm taking it there isn't a difference except in the VIN description tab in the cal.
Ok

I don't know enough to be able to say if it matters.
