Increasing plug gap fixed my issues!

Naw its not that. This sounds like a whole cluster of firecrackers going off. But quieter than firecrackers I guess.
Ever been to, or watched a road race where the cars are all racing by around a turn and the exhaust is crackling and popping as it makes the turn? Thats what it sounds like under boost.
Someone mentioned exhaust leaks- I used to have alot of them, but they're all fixed.
