997 turbo .. something is going wrong

[ysfg35]

hello there ,

i installed 3 hfs-3 kits in diffrent 997tt and 996tt !!!

but before 4 weeks i ordered a kit that came with diffrent PWM (v2) and diffrent relay !!!!

so we installed the kit in this 997 turbo , same as the the old kits we installed


but this one actting weired !!! the gauge is not active correctly as you can see in the pics .. the pump sometimes worked by itself and pass the meth , but no meth went after the FAV !!!!! the system is working crazy !!!

so what had been changed in the new system ? (PWM V2) ???


is the installtion should be diffrent the old kits ??





thanks so much
