Unhappy Pinging, knocking or detonation?? Expert tuners please assist!

O.K. here is the long and short of it.
I was testing out my FD and in every gear (well, at least 1-3) above 6500 rpm I start to hear the well known popping noise and experience power fluctuations. The plugs are brand new NGKs. A/F gauge is well into the green.
I added a bottle of octane boosters with the new tank of gas and made a quick run up to the redline in 2nd, and it seemed to have helped.
So here is my question, can someone explain to me the diff between pinging, knocking (which I think is the same as pinging) and detonation, their causes and remedies please.
I will be installing a FMIC soon, and I am hoping it will help in preventing detonation (so I've heard)
Thanks for the info.

if you dont have enough fuel, an intercooler will actually increase detonation.

Well, here is the thing. I have a Pettit unlimited ECU and I am running rich, so I don't think that's going to be too big of a problem. But can a high pressure fuel pump provide more fuel or do I HAVE to upgrade to larger injectors? Thanks
