If anyone out there knows where (or even if) there is a pressure switch apart from that nasty N-75 boost regulator switch any where else on the intake manifold or elsewhere in the motor, can you please let me know! Yesterday the ECU stopped the motor from making 18 p.s.i just because it wanted to give me whiplash in 2nd and 3rd gear.

Ta.

P.S: Car goes in next week for installation of programmable computer.
