Mike's on the money. I have a deisel now, had an. F53 and v10 prior.
The v10 loves to rev. Its owners/drivers sometime not so much.
You can just leave it in high gear, put your. Foot on the floor and forget it. It will run at 4000 to 5000 rpm and climb the hill as best it can. It won't hurt itself, tho it may soundd like it might.
Or u can learn and feel what rpm you are most confortable with, downshift manually, and just hold that rpm. I was most comfy in the pace arrow at 3500. I would downshift to third, and throttle to hold 3500 on the climb, generally around half throttle.
There are chips / tuners that will help keep it in a higher gear / lower rpm. I had one, it was great
