Is this a stock tune?

[Tapi]

Hi. I have not tuned diesels before and I started with a '02 Silverado Duramax. I downloaded the tune from the car and made adjustments to it according to one procedure I found from this forum. The outcome was a little unstabile idle and jerking on high rpm.

Later I got to think whether the tune I modified was original or not.. I found few tunes from repository and in those tunes injection timing was way less in "power areas" than in my tune.

I attach here the original and the one I modified.

No that is not a stock tune.

Thanks. I better copy the tables from a stock one and start again.
