2008 os 12628594

[knowledgeseeker02]

I'm pretty new to EFI and I got my hands on a "practice vehicle" after months of research and working through an old starlite manual, the file i pulled from the truck has an invalid checksum so i did some more investigating and believe the truck had a box tuner on it at one point in time. Used TIS to get the information i needed to find a suitable base file but I'm having a hard time finding a stock base file with the correct segments in any previous threads. Any recommendations on other places to look?
Thanks in advance

update: Have mostly all i need, the only segment im currently looking for is spedo: 12628712

The last page of your TIS list is missing, but this file matches all the segments in the screenshots.
