Any competent tuner can modify throttle tables in the tuning software to correct the throttle response issue. Your best solution is to find a new tuner.

Go for the intakes if you want. Not sure why you haven't already with your other mods. Biggest difference you'll probably find is the metal tubes will heatsoak your engine bay increasing IATs when stopped thus further exacerbating a slow throttle response off the line.
