Before the IC install I need to block off the airbox CIS pop off valve.
Until now I have used a plumbers test bung which has been OK, but the more you use boost the more it starts to bleed pressure and eventually blows out.
I think the rubber gets a bit hard/dry and it loose's its grip in the hole.

So, I've come up with a solution to block the hole where the pop off valve was semi perminatly and will try it this weekend.

Then its on to the big IC install and I will redo the FrankenCIS as I think issues wit the plumbers bung have given inconsistent results, plus it will auto tune with any changes the big IC make cause.
