I still dial it in even when I've gotten them from customers that were zeroed - I populate them and dial them in no matter the injector size. No doubt there are other tables at play, but if we can't edit them and can edit this, then I edit it to correct it. I always thought people were sending me files zeroed out where they had zeroed them out. People zero them out based on bad info from years ago discussed on the subject so I never thought much of it - I just dialed it in. We decided it was best to dial it in years ago after seeing the negatives of having it zeroed. Heck Jslic is the man that discovered this table then - I worked with him on it along with several other tables that are in hpt today.... I used efi and sct to change tables then read them out with hpt and sent them to hpt, so I understand the importance of this stuff If setup right you can literally hot soak and make back to back passes with a 1000hp car getting damn near identical passes each time. Trust me - you don't want to dial it in - it's up to you, but it can make them go pretty lean when they get hot.
