I say go with a custom setup....or I may be selling my turboxs soon. I may need money soon, but if I do another thread will be up about that....
But with my turboxs i'm seeing charge temps 20-30 degrees lower then my topmount via scan gauge. I love it, there is very very minimal lag. The fitment and instalition is good and easy.
i did some research a month ago to build my own fmic. i wanted a vertical pass fmic for fitment, 2.25 in piping, beaded pipe ends to help hold on the hose connectors, and channels in my end tanks to help even out the flow.
that is exactly what cpe made... and it is perfect for me. after pricing out the IC, piping, and hoses i'm damn close to their fmic price... so it's a no brainer what i will chose when i get mine.
the only application the cpe fmic could be lacking would be on a 500+ hp dyno queen. in that instance you would have an IC the size of a bath tub.
