HPFP , massive mid range increase (area under curve)
more aggressive boost settings (REVO)
but I suspect your biggest issue is grip, as low rpm torque just lights up tyres..
so LSD , suspension , neg camber, engine mounts, wider tyres , R888 tyres
to make it a matched setup
oh and the first thing that will go is your clutch so budget for that too (manual)
(or a DSG remap as I seem to remember your pirelli is DSG)
whilst the feel is great it can be counterproductive in making good progress.
smoothing out the delivery and maybe reducing low rpm torque may make it faster (but ironically feel slower)
