03 Case IH D40 turn up?

[stock600]

Not exactly a pull style tractor but not many post here anyways so hear we go. My 03 D40 has a inline 4 cyl. diesel and runs an inline p-pump style inj. pump, the 40 is the smallest of the 4cyl.'s and the 45 and 55hp tractors run the same engine and displacment so i fiqure its just in the pump tuning? Any one worked with one of these before? Its a great mid size tractor but for heavy use it could stand another 5-10 hp, any tuning tips? Thanks

The DX55 is turbo'ed the forty five is not. The 40 is a 2.0 liter the others are a 2.2 liter. At least they are now didn't look in the archives.

Ok, ya mines the D40 not a dx modle but, at least the next size {45} was the same displacment then, and yes it is the 1.995 L. But the question still is has anyone turned one up a little? Thanks Ryan
