The problem started long after the install of my FMIC so I know the pipes arent the cause. (Though for good measure I will check all of my couplers)
The MAS issue is a good one. I shouldn't be over running it, because I'm not boosting much, but it may be bad. I hadn't thought of that, but I had similar issues when one went bad on me a while back. Good time to find a 2G MAS.
When I last checked my injector duty cycle the spring in my boost controller was too stiff and I was boosting 15-16psi. I was getting 110% by 6,500rpm. I have since replaced the spring and am running more conservative boost. At 17lbs on my 14B I was hitting 100% around 7,000rpm.
Fuel pump will hopefully be replaced within a week with an EVO unit so that should cure any fuel pump issues.
Checked base timing 5 or 6 months ago. It was a couple degrees off. I set it. Haven't checked it since. I'll grab my timing gun next time I get to my folks place.

Definitly get a 2g mas. You may not be boosting much, but when the mas draws in air, some of it is going to leak through boost leaks, then the mas is going to draw in more air again to replace the boost that is leaking. Which ends up in your mas over running. This also makes you run richer too, because the mas is counting air that isnt getting sucked in by the engine, but rather being dispersed into the atmosphere via boost leaks, and your ECU doesnt know that, so its reading more air, which means its going to send more fuel. This also then raises the injector d/c to a higher point than it should be, and causes the fuel pump to not be able to support this much amount of fuel that is needed. So all of this is going to account for your car to go FDRTHRTHAEFGARHGFDVXVBAR!!!
So...
FDRTHRTHAEFGARHGFDVXVBAR!!! = Knock
Well, atleast thats what I came up with, lol.
