ahh - and how do you quantify this?
logged n75 duty cycle before fitment and after? likely higher duty cycle after to overcome additional losses.
I mention it because, several years ago, when ibiza cupra's were new, someone came up with a dual pass fmic.. several people lept at it as at the time little other available items were about.. Now they definately had lower ait temps once fitted, BUT, also lost a few psi across the core, as some of them running high boost found out. (they had lost boost) but gained lower ait's. All of them were loosing pressure from the effective longer core, and n75 duty cycles where not already max'd were higher as the turbo had to work harder to achieve its boost and flow.
unless you have logged before and after, you wont be able to quantify this so well.
