thered be no way to tell. the last dyno run i made was with shortys now i have longtubes. i guess i could always put it to were the CAI should be then put it like this and see. i dont think itd do anything just gave me a reason to put a hood scoop on. 60+ it pulls alot harder then before. i guess i could give it a shot when i get dynotuned ill letcha know.
