Mine is not just a consistent ticking - like a consistent or rhythmic noise... it's sporadic, and the ticks will sometimes be back to back - or spread out by a couple seconds...
Almost always gone above the 1600RPM range -but for the first time - a week ago, i heard it at WOT in 3rd gear. From like 3k to 5.5k i heard 4-5 Ticks, that were audible above my B&B Bullets and DTE Supermaxx LTs...
If it's detonation - what should i do to start fixing it? What causes this? Would i be able to easily diagnose detonation on a Dyno?

You run lower than premium gas
Your car had an aftermarket tune that got too aggressive
You have a malfunction in your sensors or computer.
Long tube headers usually make yuor car run richer, making it even harder to get detonation on a stock tune.
Scanning software would tell you pretty quickly, you don't need a dyno, just something that measures A/F

i have the same tin can noise only when in gear hitting the gas light or hard. goes away if you let off the gas or hit the brake. car is a 97 auto all stock. had the car on a lift today cant duplicate the noise has to be on the ground with restriction. no noise if not in gear or if you try to power brake it . changed plugs and wires thinking it was a ping no diffrence. everything seems tight under the car. is there a way to check the cats? they seem ok when you bang on them . need help out of options
