Hello evreyone i Currently have supra downpipe tune but I'm currently in the process of doing a custom tune and bellow I will attach the data logs to read if anyone can help but my question is my tuner sent me a revision for the tune and I'm looking at the knock retard cylinder 1-6 and it was showing up to -6 degrees knock on all cyldners and then the lastest revsion he sent there is 0 knock all around on WOT but their car feels so much slower so my question is, is 0 degree knock what most custom tuners they sacrifice power for the engine longevity or what I've also heard is some add 1-2 degrees of knock to give more power but someone please explain to me better if I should stay somewhat slower at 0 degrees of knock or ask to turn it up a bit more with knock and also is negative knock bad or good I never had positive knock, just negative Also, this is a flex fuel tune but we are on 93 right now we haven't moved up yet.
Here are the data logs labeled knock and no-knock:
