I had a 2004 psd 6.0 with a superchips and exhaust only. That truck went 14.10 in the 1/4. What should i expect my 2007 6.0 to run with your fastest stock safe program.
It's difficult to tell what any truck will run because there are too many variables including how you drive. Typically you can see anywhere between 13.5 and 14.5.
