Tunes i found that are available for my 2015 chevy impala limited LTZ.

  • Trifecta
  • Overkill
  • IPF Tuning
I have looked over all 3 tunes, based on their proven dyno charts/Power Claims. Does Anybody have any experience with either of these tunes specifically?? How did it compare to what was advertised on paper VS real world driving conditions??
I will be posting screenshots of dyno charts and from my research the IPF Tuning seems to be the best tune available, although no posting of it over the impala 3.6 LFX... not popular or more new than trifecta/Overkill??
