2008 6.4L take-off

[greggandsons]

U7164 9v03. Why is it that at take-off I lag for a moment. In every tune it happens as well as stock. Also, my tuner does not have an area to modify tires. Can I set my shift points or something to make it take-off when I floor it?

I believe thats just the dual scroll turbo lagging.

Modify parameters should come up on the same screen that gives you the Install Tune Option.

Thanks
