I think it depends on your personality too.
If you like to "tinker" with things, I would go for the turbo.
Personally, if it were me, I would go for the turbo...(And I would try to make the "turbo whine" so loud, it would be like a Big Rig struggling up hill...

...hahahah)
Obviously, the other "bonus" (at least for me) is that you get the added power
without being married to a "factory only" computer system....For us guys that do their own work, thats a big plus

When I was looking at tractors, the 2 HP ratings above my 2501, they did't
WOW me in regard to their other "superior" traits.......

However trading up to a larger tractor would be the "simplest/easiest" solution if you do not like to work on your own stuff.
Since I have not researched the "fuel pump" thing much, it's hard for me to say, but my "Spidey Senses" tell me it won't be a huge improvement.,,,,but I'm frequently wrong
