West Palm Beach and overboost switches just don't get along I guess...

I live there too and if i get on it with the wire on the overboost switch it'll shut off the fuel pumps at around 9bar everytime and leave the car and me on the side of the road...
That switch on mine must be used up because it won't let the car start until I remove the wire from it and ground it.
So, I have a little male spade terminal mounted on the intercooler next to the switch now and the overboost wire stays on it now. . . works great.

If that stupid switch wasn't so ridiculously overpriced at around $75 I'd buy a new one, but it should be no more than an oil pressure switch at around $10... so forget that.

I have the VDO mechanical boost gauge with telltale in the clock hole and it shows peak boost at just over 9 bar with a K27HFS turbo and B&B headers on a 75 degree day so I just leave the wire grounded and enjoy the car.
