I think you have more problems than just a tin bit of knock. Your first WOT blip, shows up to 3 degree's very briefly, then your next long WOT run shows hardly.
Some tuner you got there if he can't even see that you are at 123% duty cycle and that your commanded AFR is stupid rich at WOT. You ran out of injector a long time ago.

If you don't post your tune and logs when you have questions you aren't helping yourself.
I feel dumb , I see it now during the small burn out then again in 2nd going in to 3rd , I dunno why I didn't earlier ok thx , also here is another run about 30 minutes later from a older tune I modded my lambda looks better , now a 750 to 800 for a boosted application is prime for lambda ?
You're still out of injector, upwards of 97-98%.
You have also maxed out the MAF sensor, it gets pegged at 86 lb/min. You'll need to increase the intake tubing size to get the MAF back in check. Going up by half an inch in intake tube size should work.

The Maf will allow up to 529 lb/min, the OP is nowhere close to that. And the fuel needs to be leaned out a bit (I would use .810 commanded EQ) and tune the Maf to get the actual Lambda to match, thus lowering the IDC%. The injectors will be fine then.
I wouldn't worry about the odd 2* or 3* knock retard.

Ok thx for the response , I have a 5in CAI with matching MAF , I was hoping that was not maxed out , I'm on E85 with 1000 ID injectors , along with dual nozzle meth injection , thx for your input
