Additional question, what if I was to switch between my stock and stage 2 tune would a CSF IC still be good to have or would I need to switch back to stock IC?
Any time you get a bigger intercooler, there will be a pressure loss but when you are on stage 2 the pros (lower intake air temps) outweighs the cons (higher pressure drop)

If you go back to stock map then the cons will outweigh the pros


In your case i would recommend a 5" intercooler like Wagner EVO I, VRSF HD or Active Autowerke. It would work well with either the stock map or a stage 2
