What you guys like about my 2011 silverado with the FPCM. Running one of the 450 and another 450 coming on under mid boost and up to WOT???

 

ive skimmed through that post a time or two, ill have to actually sit down and read it when i get home from work today. another thing i forgot to bring up would be fuel rails...im currently just running the factory TBSS rails that came on my intake. should i look into upgrading those as well or with the rails be okay? if i do need new rails, i have no idea what to even look for to fit a tbss intake and my current injectors are the tall style, not factory length. dont know if that would make a difference or not for the rails.

 

I bought zachmans d1 and im having the same fuel issue. I want to run the holley dominator dual on a hob switch from lsxtune. Ill need a fpr, rails, and lines. what do i need to do to the bucket for pickup? Ive also looked for a returnless to return thread with not much in the way of diagrams.i dont see why there isnt a sticky for this yet.
