Ok, has anyone tried a bigger MAFS and bored thottle body along with their cold air intakes and cat-back systems. On my past truck this combination seemed to give better results than just an intake with a cat back.

 

I haven't seen anything that indicates that either are available...yet

 

Makes sense, I would think to to see gains one would need to replace both the intake, mafs, and the tb. Was the intake plenum matched to the tb?
