The dyno graph below is of a F150 but the same applies to the Mustang. With swaping intakes, it really depends on where you want to make power. If you want low end torque and a nice mid-range, nothing is going to touch the F150 manifold. Without question though, the Mustang with the 2018 GT manifold will be the faster vehicle. The curve below would have stayed flat all the way to 7,500rpms if the truck had a higher rev limiter.While ultimately up to him, spend the time and money to do a swap that gains nothing down low over a stock intake doesn't seem worth it to me. Now if he does it and enjoys the high rpm gains during his seemingly rare visits there, then it wasn't wasted at all.
