What OS number are you wanting to use? I might have a trans segment that would work for you.

WOW!!! WOW!! WOW!!! To all of the gentlemen that have worked so hard to make this a reality, my hat is off to you all. well done!! I just gotta get it setup lol. I have been using EFILive for a few years now, still have mixed feelings about it. I do own a licensed version of Tuner Pro RT just hadn't worked with it much, I guess it's time to get into it shoulder deep.

Thanks again for the work past, present, and future.

Hi i'm new here, first of all thanks LRT for the great work, second does anyone has a 9381344 OS XDF File? I've find only one for a F body and i'm not sure it'll work in my 4.8 out of a 2000 Silverado that i'm currently swapping into my 77 2WD K5 Blazer
