Worth it? Depends on what you're paying, what you expect!
The Punto 75 put out about 15bhp more than the p60. It had, MPI, different map, bigger throttle body, better manifold and exhaust. 
Set it up properly and I think you might see 5bhp. 
To my mind, a bigger TB and a chip will give you more, with a p75 cam, more still.
To put it into some kind of perspective, my 1242 Cinq would be marginally beaten by standard Binis with P75 cam, decent exhaust and GSR. Once I put a tricker on a Panda 45 inlet mani it would have them.
