Any side effect to moving my adjustable fpr from under hood back to the rear?

Is there any side effect to moving my adjustable fpr from under hood back to the rear? pro's , cons. I assume if I make sure the pressure at the rail is the same , should run the same.

I see a lot of high hp cars put the regulator after the rails, I really don't want to do that if I don't have to.

Is your FPR manifold-referenced...? If so there might be significant MAP signal lag if the FPR is at rear of car.

Yes its manifold referenced
