    Seen your post on the corvetteforum.... I assumed it was bc of the driver mod, however if you post the tune I'm sure we can dissect it.

    Just finished looking at a tune from a "professional" shop and it is TERRIBLE.

    Peak Tq is maxed out, makes me wonder if this rig is even going into PE mode? Who tuned this?
    The top rows of the DD table is way to high

    LOL you don't have any knock coming from this rig, its basically disabled. I wouldn't play that game.
    Your pulling a pretty high Cyl load at wot making 600rwhp so Its showing around 14 degrees of timing.
    I know A&A, they don't like Meth so I assume this is for 93 octane??

    The SOI table is interesting, looks like they at least tried to do that correct

    PE is fine with the designated stoich (I assume since the MAF is modded, they are hitting commanded) AGAIN, hope the Peak TQ table isn't effecting this, since the tune is still using enable tq as a PE qualifier.

    OVerall its not a bad tune though, just a few things need to be changed in my opinion.

    EDIT: your LOW octane table at WOT is higher than your High octane (that's a fail) its pushing around 16lbs. That's a lot of timing IMO on a Gen 5 with close to 8-10lbs with regular fuel, 14 IMO was pushing it

    Can you get a WOT LOG??
    I can post a config for you if you want and you can just load it in the scanner and then hit scan

    log shows 4degree of timing being pulled at higher rpm due to intake air temps being up to 130 degrees is that correct

    The new tune is MUCH better, PEAK Tq table looks pretty correct, KR table is modded well imo, DD looks better, Low octane table looks better.

    You didn't use my config so I am not able to look at what I really wanted to, but that's ok. The new log I ASSUME is with the new tune, its going into PE nicely (I bet it was not before)
    THE IAT VS spark is there to help, you want to keep the IAT's down spray some meth or get a better intercooler.
