Makes sense. Thanks haha

I know spark knock is bad (first car was a turbo 300zx) but now I can view how much knock there is with the trinity on my truck and I'm wondering how much is harmful. You don't want it at all just seeing if you're safe with a certain amount. 2010 chev 2500hd 6.0

Needed a new ecm it's all good now. What octane is the Diablo tune for I'm seeing no changes in anything with 87 tune

Hey I just received my trinity V. 1r13n and went to tune my 2010 6.0 chev with no luck. Can't back up my factory tune therefore no go on the tuning. First programmer I've owned so I'm new to this but what needs to happen for this to work?
