FPR solenoid only works on startup, it keeps the FPR from seeing vacuum until the engine is running. Has no effect once the engine is running.

Ok I guess I'm wrong again? Have you ever actually checked it to see when it stops venting to atmosphere after a cold start?

Actually the reason I recommend disconnecting it is they are known to leak under high boost thus lowering your fuel pressure causing a lean condition at the worst time, but I'm sure you already knew that too.

Hummm I guess this post must be useless information? Good thing you know when it shuts off tho that's way more important than saving your motor.

I'm actually fairly disappointed with you evoIXer I've bent over backwards to help you with this problem and told you exactly what to do too fix it. What I've told you is no BS and will solve your idle issues. But you end up thanking someone who has done nothing but tell you wrong and miss leading info? He's not trying to help you, he's just trying his hardest to discredit certain people on this forum who have not agreed with him in the past. I tried to help but I guess since certain folks have 7000 posts they are more believable?

Are you confusing me with the OP? 
Don't get me wrong, I am learning as much as I can because I will eventually run into this problem myself. Hopefully, I'll know exactly what to do then.

What kind of injectors are you running? I'm running ID1300x injectors and my idle is smooth as silk even on pump gas.
Did your tuner properly set the latency and dead times? What kind of trims are you seeing at idle?
