I can't see how you would get 43hp from a tune. But I have been proven wrong before.
We are talking about Euro spec, so both 323i and 325i are N52B25 2.5L engine.

One of the main different between 323i and 325i is the rpm limit, 323 limit at 6500rpm while 325 limit at 7000rpm.

A tuned 323i has higher torque but still cannot get pass 6500rpm, so it cannot be in the 325i level.
If the car has 230nm of torque, then 500 rpm locks around 20 horsepower.
