Understandable. Going by what a stock 6.4 with our 310 did at Rudy's Open House on Dunbar's dyno, I would say it's more like 10-15 horsepower from 600. I can't think of the guys name off the top of my head, or his username, but he did 586 uncorrected. Stock truck other than the tuner, intake, and exhaust. I was impressed, especially with it being on Dunbar's dyno.
Im pretty much identical to your truck as it sits so ya id say its a little higher...we'll see, im gonna get some dyno time soon before and after some things happen
hopefully by summer im seeing at least 200 more...then spray and prayimp:
