What would I need to do to make fast 85# ls2 uscar injectors work on my flex fuel 2011 gmc sierra lc9 5.3 with stock rails and truck intake?

Correct injector data and possibly spacers if the injectors are taller than your factory injectors.

They are better options out there than those fast injectors that would directly swap in with known data.

Why such a big injector? Do you have any other supporting mods that requires something that big?

My 2011 gmc sierra 5.3 lc9 flexfuel truck is currently cammed, stalled, & I removed the dod/vvt. I'm in the middle of gathering all the parts to turbo it. I was originally going to use FAST uscar ls2 injectors with fuel rail spacers but due to no data for them I decided against it. I was told that (siemens deka mototron high impedance 80lb. ev6/uscar mid length 48mm injectors are direct drop ins for the nnbs stock truck intake & fuel rails.
