New here, just got my I3 for my 18 Silverado 5.3. I’m not interested in running 91+ octane, for now, so I modified the 87 tune. Who on here has serious results with this? I only turned up spark advance 1.50 , afm and cags off of course, firm shift, 4% throttle boost, and have to admit… it’s nice. So much more responsive.

adding timing on 87 is a bold move, I'd log for KR ;)

Kr? And you’re saying I shouldn’t? I enjoy the extra power but not at the expense of the part’s safety

Do not add more timing with the 87 tune... or with any of the preset tunes... I actually end up having to lower it a little on custom tunes for people due to knock retard they have even with the preset tunes as-is... so no, do not add more timing.
