2007 will be very very different from 2009, are you sure that's what you need? And they are in the repository. I don't know what you messed up when searching but they are there. Probably a few dozen.
What engine RPO/8th VIN are you looking for and not finding?
I am Installing a 2007 NNBS Complete whole 5.3L with Flex Fuel Intake on my 2003 Yukon Denali 6.0. I have presviously tuned my Denali over the years and want some 5.3L Flex Fuel tunes, so I can reference what they have for fuel injectors and other flex fuel data. I'm also going to add the flex fuel sensor and do a patch on my PCM, so my 6.0 is flex fuel.
2007 there were two different "5.3L with Flex Fuel" engines - a Gen 3 version in the 'Classic' (that flex engine RPO is L59, which uses the same 33/35lb 12580426 injectors as all the previous years' L59), and the Gen 4 non-Classic (flex RPOs LMG/LC9, with 36lb 12594512 injectors).
