From the HD graphs - the boost IS a tad higher and definitely gets held for longer. Which is what you want to do, as the cooling capabilities and core size have both increased - can run and hold more boost for the same knock threshold, perfect example of a mod that frees up power.
What fuel is this on (P100 from memory?). That torque curve looks fantastic (well done!), do you feel the difference?
PS. IMO get your tuner to fix that 'dip' in the torque and power and the boost fluctuation. Your tuner brags about how smooth his power delivery is - get him to deliver!
