Another Tuner Question

So I've been researching like mad about tuning, I have an 09 6.4 F350 SRW.
I'm going to be going with the H&S tuner and delete pipe and I'm just curious what can this truck safely handle?

I know I'm going to want to at least launch the truck with the strongest tune just to see what it does. I'll probably keep it slightly tuned unless there's a chance of any damages.....Anything I should be wary of, parts breaking, anyone run into any issues?

Thanks!

My understanding is that the highest tunes are also where you see your best fuel mileage, but I have decided that I cannot keep it in those tunes. It is just too easy to romp on it. I keep it in the easy tune, mild setting which is better for towing and engine longevity.... I think.

Even at this lower setting,the truck has more power than I can ever legitimately use. But its still damn fun to romp on every now and then.

My best advice is closer to stock when towing..if not stock power level.

I have run mine at the 300 hp tune to check out mileage but usually run on a low tune, have not seen a big difference in MPG between the two.
You might think this is silly but I HAVE NEVER had her over 70% throttle either. Absolutly no need, it does get out of it's way really well.
