I am sorry if you have seen this post before but I seem to be putting it in the wrong places and have had half a dozen different answers.

I have a 95GTB manual, it has developed a strange fault whereby the boost presure is too high at high revs and the ECU shuts off, a manual guage shows anything from randomly 1.3 to 1.6 when the power is instantly shut off, lifting off momentarily stops the engine shut down. I have been told this is due to a failing waste gate valve or sensor that is sticking.

I wish to fit a dual solenoid boost controler, would this device replace the supposed faulty valves, if so can anyone recommend a reliable product.
