Old S300 to New S300 on my P28

I have inherited my dads old race car with a P28 OBD2a and first Gen S300 #7864. I am told it was locked by a tuner back in 2009. We just rebuilt the engine and I am curious about how much tuning I can do with a locked system? I am new to this, like yesterday new. Can I just buy the Hondata upgrades ...
