Hey everyone !
ive been having problems with my ws6, m6.. lets see how i can put this...
. when im driving and im about to hit a red light.. i put my car in neutral then just slow down with my brakes.. obviously.. but when it is in neutral and me slowing down my Revolutions rev up on theyre own.. up to 2500 and dont come down till i make a complete stop.. its been wasting me quite a bit of gas lately.. anyone know what the possible problem be?? i was thinking something to do with my throttle position but when im completely stopped its all fine..

To Me, it sounds like a tuning issue. Has it been reprogrammed ?

the only thing that was reprogramed was my fuel injection timing. . could that be?

Yes, that can do it. Hope the tuner is local and can correct it for you.
I've had simular issues, that I tuned out with the HP Tuners software.

Mine did the same thing for a while. I haven't tuned it or anything. I would sometimes just turn the car off and start it back up. Helped a few times, didn't help other times. Haven't done anything to fix it, but it hasn't happened in probably a year or so.
Just recently, I had issues with it dropping RPMs to as low as 400 or so when I came to a complete stop. Didn't stall out though and it hasn't happened for about a week.

Basically, you're not alone. But mine just stopped having the problem without a fix at all.

Is your throttle body drilled? My car did this exact thing, previous owner had drilled the TB causing a "hanging" idle.

I would say no, it's not user freindly at first !!! But you will catch on, you can email tunes back & forth, look at other tunes, ect !!! I thought it was frustraighting at first, but now it's the best money I've spent !!! I'm even tuning my 03 6.0 Suburban now for better pulling power !!!

That is kinda interesting about emailing tunes back and forth, can you acually put someone elses tune in your own car or just look at the tune?

If you would send me your tune, I can't edit it & send it back ( unless I would use credits ), but you can copy & paste the different fields into your tune. When the time comes, there will be alot of help & advice !!!

Knock on wood.... I think I might have found the prob, I turned the idle down by moving the idle set screw and everything SEEMS to be good i'm gonna drive it some more (weather pemiting) and see how thing go. I will let you guys know how things go as I get to drive the car.

does it do it just when you put it in neutral, or when you press the brakes in neutral. I know if its the brakes it has to due with the vacuum in the booster, it can cause surges.
