These two things don't require a dyno tune. Goes in and goes out don't change so its "within the bandwidth" of the existing ECU.
My $0.02 - I think the spacer provides more volume right above the intake, so there's less of a vacuum increase during throttle transients, and the ECU doesn't see a sudden demand for power that isn't being met. My truck downshifts significantly less on uphills and mid throttle acceleration efforts like entrance ramps with the spacer.
