You go to VR3003 on the IF board. My V Field only put out 90 watts on 160 meters from the factory.  The rig will put out up to 200 watts on CW but I set it to 150 watts max. I run allot of MFSK16 and RTTY at 150 watts with no power supply or finals problems. The power increase mod no no is just another ham radio urban legend. I've also run my FT-990 and FT-840 at 150 watts for years with no problems. There are some appliance operators that can screw anything up so the rig manufacturers write the manuals for the lowest common denominator.
