combining performance enhancements?

I have a 2015 eco with the GDP plug and play which I love. Silly question Here can you use that with the GDE tune to further increase performance or is this overkill?
I was just wondering since the GDE is a tune and the GDP is more of fuel pressure increase from what I have read.

Well i called around and it's either this or that, but not both. I'll stick with my GDP 23.5 to 24 highway, dragging heavy bass boat 17 to 18 mpg at 75 to 80mph. Did not know if anybody tried this. Love my ecodiesel, rides as good as some of the bimmers i used to own.
