    I've seen it noted that, in stock form, the B58 in the Supra knocks slightly during dyno runs and pulls timing. Can anyone confirm this and possibly provide numbers?

    Thanks

    this is normal. EVERY engine since the beginning of internal combustion engines knocks a little bit. Its inherent in the design. corrections up to -3 randomly or not across all cylinders are accepted.

    How much more knock is there on 91 compared to 93? Does adding a few gallons of e85 remove most of the knock on stock tune?

    sure it'll help. but you're still going to have corrections here and there.

    Correct. I was more interested in how much timing was pulled when running 93 in order to ascertain if meth injection alone was a worthwhile modification. Ultimately, some degree of tuning should be done however what would be results be without tuning?

    Thanks
