[QUOTE="metaman, post: 8458235, member: 23647"] If you hook up the bypass directly to the post boost vacuum port on the blower you should not have this issue. My car sees IAT's identical to when it was hooked up to the solenoid when cruising. The whole idea is to completely take the solenoid out off the picture. So it should not matter if it is turned off in the tune or not. The results should be the same. The only way that you would have the issues you described is if you are not seeing vacuum from the line you connected to the top port on the bypass valve. Hook a vacuum gauge up to the line you pulled. You should have full vacuum sucking through it at idle. If not then figure out where you hooked into, because it was the wrong place. The only reason the solenoid was designed into the system was so that the computer could pull boost if you got into a extreme high IAT's. It worked perfect at 8lbs of boost. However, the boost dump solenoid was not designed work at higher boost levels. [/QUOTE]
