Okay so what I figured out tonight is that there's three wires that went to the T5 solenoid. Obviously you only use two one of them is 12 volts when I hook up a multimeter to the other two neither one of those go to ground. I have two other cars I've done this to another words gotten rid of the T5 valve had the ECU modified and they both work like they're supposed to. So does that mean there's something wrong with the ECU I am not getting either one of those wires to go to ground with the key on and hooked up and also with the key off and hooked up. I hope that makes sense I've swapped out another mosfet because it tested bad now all three mosfets test good but I'm still stuck in base boost because I don't think I have either one of those wires going to ground I'm pretty sure it's not the blue wire because the blue wire is not hooked up on any of my cars that I've done this modification to so I will concentrate on the one wire. The car has had plenty of boost the whole entire time and then all of a sudden I started getting over boost and then that started us down this road. So to sum it up I am in bass boost right at six lb. So I will go follow that wire back to the ECU and make sure that there's no break in it if there's no break in it I'm guessing there's something wrong inside of the ECU because it's not grounding it? This is not the same ECU that I had in the car before with the T5 valve. But this ECU has been modified and was still giving me wide open boost. So I will try and track down and see if that one wire has a break in it. Sorry for the long drawn out text. So we traced the wire that goes to the ECU it does have continuity it is solid it has no brake in it all the way to the ECU
