Help on Supercharger Tuning

[Monster_boy]

I am currently running a Blitz Supercharger on my GTS.
The ECU that i am using comes as a package with the Supercharger tuned by Blitz, but the response is not as good as expected.
Can i know wat other ECU systems can be used to pluck and play on this Supercharger system so as to tune it to be more responsive and gain more horsepower out of it ??
Is there such a thing as Supercharger overhaul maintenance ??
Tks....
