Im planning on getting a c&l plenum and Acufab tb, i already have a jlp ram air and c&l smooth tube up to the stock tb and an 80mm MA. I am running a Predator and i was wondering if i will need a custom tune when i get the PL and TB. thanks- Kyle

 

more than likely you will need to tune your truck for the TB.

 

i would up grade to a 90mm mass air, and then get tuned..
