As the title states I'm chasing knock and it's always been off and on. I want to say it's false knock but why chance it. Basically in less than a years time the car has had some new parts put on. New ls1 MAF from TT, ac delco fuel filter, deatschwerk 300 fuel pump, racetronix hotwire kit, im on my second kirban fuel pressure regulator and I believe this new one may be messing up now. Lucas green band 42# injectors, Terry Houston downpipe, TA-49 turbo, rjc cross flow exhaust, car has had poston headers on it for years now, I recently replaced the ECU, i put a new ICM, new IAC, new Bosch 02 sensor, it has a kirban voltage booster, rjc booster controller, new 120amp Alt, new serpentine belt, razor alky kit, I have a rjc front mount but not installed. MSD spark plug wires, spark plugs are 2 degrees colder than factory so 42 I believe. I'm probably forgetting some other small stuff. Anyways it seems like I can get the car to not have any spark knock but then a week later it'll be back. I believe it's false because generally it'll always show a crazy number like 6-8 degrees of knock basically as soon as I hit about 10psi of boost. Every time I've gone full WOT and had no knock my 02s were in the low 800 range. I just recently put the ta-49 on and 42# injectors. TT alky chip, 93-94 octane, 23/21 timing and 23-25 max psi. Now I have not gotten it to 23-25 right now it's set at 20. And before it was able to reach 20psi with no knock. After install of the last 3 mention parts above I did a pull and got maybe .3 knock at shift and disappeared, car pulled hard and felt great. Now last night I put on a new Hotwire kit because my old one so happened to shit out on me after that. Did a 3rd gear pull where I eased into the boost and I had no knock. 02 were at 808. Except when I let off the throttle I could hardly hear the iconic TB turbo flutter. Went to do a pull today and boom knock showed up at 8.9 at around 10psi of boost. This is all strange and I don't wanna keep throwing parts at it because I feel like there's maybe something I'm not getting here and my issue is very simple. Car runs great, idles very nice, little rich FP is set at 45 line off, but for some reason it keeps changing. Not even a week ago I set it at 45 line off and it went to about 40-41 line on. Well now it's reading about 45 line on afters it's warmed up. Any help would be appreciated, I just want to see how quick my car is but I can't if I keep chasing knock
