1999 Alfa 156 2.0 TS Error Code

I have a huge flat spot after 4500 rpm that kills the power. When I disconnect the MAF the car wont idle but the flatspot seems to be gone. Just to be double sure I have connected up my laptop to FiatECUscan and got the following code P1173. Does this relate to MAF?

Also I wasn't entirely sure what my ECU version was. I used Bosch Motronic M1.5.5 as it seemed to connect and read the code ok.
