What I had in mind was to install a manual boost pressure control where I could make sure the boost was at 14 psi then disconnect the EGR valve. When I disconnect the EGR the computer cuts boost pressure. I would be bypassing the computer and controlling boost manually. I think on this car that the ALDA works off of boost pressure only and has no wires going to it. Therefore the computer could do nothing to cut any power. I have tried every way I know how to disconnect the EGR and have been unsucessful, but I think this might work. Any ideas anyone.
