I'm about to tune a truck for the first time. The owner wants to stay on 87 octane. How much timing is everyone adding without needing more octane to combat pinging/detonation?

Also, what shift points would be best with a 219/222 .563/.566 115+4 cam and stock heads? We will not put the truck on a dyno to be tuned for a couple of months, so I'm looking for safe numbers right now.

 

that cam should pull up there. I'd say 6400-6500.

 

i would try the 30* timing range and see what is up.

 

I would say anywhere from 2-4* across the board for timing. Do you have any scanning capabilities? You could add timing till you see kr then back off 2*.
Is this cam in a 5.3?? If so it is probablly going to want to shift in the mid 6K region. I have mine set @ 6100 with my 214/216 113+4.

 

Is that the way to go? Im just curious so I know when I start doing my own tuning

 

Yes, I have Autotap to scan with.

This cam is going into a 5.3. Has anyone had internal problems by revving a stock 01' 5.3 to 6500?
