Done quite some research on 24x conversion would like a little more insight on how setting up flex goes I should be able to segment air and fuel tables into the 5.3 tune but is flex it’s own fuel...

l31 in both tahoe and c1500 using tunerpro pcm hammer and 411 have a express basemap ive looked at has anyone messed with flex fuel was wondering if theres a l31 flex tune if it would even work
