Awesome, thanks Ron. I guess I always had the understanding that your HSN had nothing to do with the idle. That your LSN and idle screw were the only things that effected the idle. So, I take it the issue with my high idle is more or less the engine and chassis temperature heating up, along with the slightly lean tune that is my problem? I usually compensate for temperature, so I am decent on that. Again, never had a flameout with my B5, so I was even thinking its me overreacting to something that isn't a problem at all. I will start with the richening of the HSN. Glad to hear that it shouldn't effect the performance too much. Thanks again, Ron. Appreciate the help.

As your idle starts off ok and then increases at the end I'm going to guess that you are probably a little too lean on the HS needle setting. Keep in mind that your tune is going to fluctuate depending on the weather conditions but next time try richening your HS needle 1-2 hours before you first go out. When you are still on the box you might find that this causes your idle to be a little too low, if so do not touch your idle stop screw just lean your LS 1-2 hours to compensate which will bring your idle speed up. Then toss it out on the track and let it rip for a bit and see what happens. More than likely as mentioned this will take care of your problem and not affect our overall performance (bottom, mid or top) as what we did was simply change the needle balance a bit
Let me know what happens!
