KR issue, need help

Alright, so I've been having a decent amount of knock and I can't seem to figure out why. For my mods, it just doesn't make sense.

First things first, mods are as follows, L32 engine, n* TB, SSAC headers, 3" high flow, 2.5" catback, 1.9 modified rockers, 180* t-stat, 104 plugs gapped at .050. 3.6 MPS


See about 2* of knock at the top of first and 2nd it's about 6* at about 3500+. It's not false as i've taken the belt off as well as dropping the timing to 10* and it goes away. I've tried replacing plugs, changing the gap, going colder t-stat (car never gets hotter than 170*). It just doesn't make sense to be knocking that much on 8psi.... Now I do have an exhaust leak at the rear crossover just cause the band clamp isn't sealing like it should so I can't tell you my correct AFR. But the PCM is commanding 11.7 and my wideband reads anywhere from 10.8 to 11.2. Anyone have a sollution, or better yet, anyone local willing to try and help me out?
 


stock front sway bar?

Who tuned it? If KR is going up, it must be leaning out unless something else is wrong.
 
The MAF is still on a box ZZP LQ4 tune. I'm gunna fix the exhaust leak tomorrow and see what happens.
 
Any box tune needs to be tuned further... because your trims vary according to weather. I had my car tuned for winter... now I am MAF tuning it again... to get my summer tune straight.
 


Well I'll see what I can work out.. I wasn't sure if the heat of CA would be a variable seeing is all the vendors are on the east coast and I know they don't see 95+ weather like I am now haha.
 
Alright, update. Wrapped my intake with insolation wrap, changed my plugs to 103's with a .050 gap. Then I fixed my exhaust leak. Turns out if was actually comeing from my EGR port that I blocked off. Took it for a spin and now i'm only seeing 3* of KR.. Could this just be pre-ignition from too low of a gap?

Probably not.
