Here are the files I have from TD.... Is their anyway to verify these are the proper tunes for the 3” systems??
 

Your fine except the stock tune.
NYTurbo is right - you're in good shape. Here's what I have - same versions as you.

Besides, I'd trust what Mike and Ben say more than what you might find on TY about your specific tune files, if they say you're all set, you're all set. They've never had a burn down since the first version of EcoTrail hit the snow in late 2016 and I'm certain they're not about to let one happen now. Their tunes are 100% proven. Why are you questioning it?

I’m questioning it because on fresh 93 octane I’m getting knock on 270 PT.....

Oh, that's right, forgot about that - did you send your logs to TD? And did you try going back to the stock air box to richen it up and rule that out? Or even just wrap a towel around the CAI filter, that would richen it up big time.
 
And I have to say, it's really difficult to concentrate with that damn avatar of yours o_O
 
Well i don't have the logging option... I am going to hookup my Wideband next week when i get home.... See what my AFR is under boost. Then I ordered a quiet core insert for my Heartbreaker. So that will richen things up as well if i need too. I will also try the stock box if i need it... Im also gonna change around my clutching..... Im hoping to have it running right by the end of next week... Guys say i won't damage my engine if i get knock because it will pull boost.... But i'm not seeing that.... Boost seems to stay at 16.5 even when the knock light comes on.... I need to get this figured out before my MI trip in Jan....

I don't think the knock protection limits boost - but it definitely pulls timing. Not sure how much, but I remember Ben explaining it would pull enough out to stop any knock, even with the big boost tunes. I wonder if it could be some other engine noise tripping the sensor.
 
Yeah.... Could be... Or possibly a bad knock sensor... AFR will tell me what's going on for sure i think... Won't knock at 11.5 or less...
 
Some things up , never ever seen knock on power trail and with 94 at that Get in touch with Ben . Could be fake knock from clutches or something. I've run 87 on Power trail and never seen knock.
 
I appreciate all the help guys.... I will update on my findings when i get it out on the lake Wednesday!!
 
Do you use your phone for live data view? Curious what the ping count is, if it's only a couple it could just be some other engine noise like @NYTurbo suggests.
