93 silverado with 2001 5.3 with a swap specialities stand alone harness running a tuned stock ecm it has a 76/65 mm turbo 80lb injectors walboro 450 fuel pump steel braided fuel lines efi 3 bar map sensor 2 step oil catch can mini spool in the rear btr stage 3 truck cam ls3 valve springs 12psi of boost
Bought the truck with the set up I’ve just noticed that he had no o2 sensors hooked up and there is also not a maf sensor so how would this be able to control fueling? Has anyone else ran this set up and had good luck with it? I don’t know anyone in my area that tuned forced induction

 

no MAF usually means it's speed density tuned (running based on MAP sensor). the lack of O2s is weird.
the BTR Stg3 still has something like -4° overlap, so it shouldn't bleed off pressure, however, i ain't too familiar with how turbo cam specs differ from supercharger specs.

 

 

probably could've worded it a little better (especially since i have that cam in my truck)
i meant that, though i'm more familiar with how supercharger cams work [since they're speced differently than a turbo cam would be]), i ain't too sure... but i'd expect it to be fine & not as bad as a bigger n/a cam would react to boost since it keeps more low end power due to still having a little negative overlap.

 

the stage 3 truck cam? 218/224? Itll be great.

 

Open loop speed density takes the MAF and O2 sensors out of the equation. KK Performance in Little Rock or Gwatney Performance Innovation in Jacksonville, either could help you out if needed.
