Taking it to a dealer, and opening a warranty case for this may help them determine the cause.

When I don't work 14 hrs a day and can have my Girlfriend or wife pick me up I will do just this but it is Friday and they will most likely not be working on it until Monday so until maybe then I will drive it for now..I just relized it had a problem on Sunday night.
The girlfriend/Wife was a joke..
I really do need a ride..HAHA.

No worries - just wanted to put it out there.

Unless you live hours away most dealers will give you a courtesy shuttle ride home.

Received my K&N air filter and drove for a couple of days and it's better but not fixed.
Taking in tomorrow will update as soon as I can..

This is a little off topic, but since you are talking air filters, have you thought about the RotoFab for a CAI, on the new ZL1?

For 5hp?

When you down shift into second gear and floor it it will sometimes hit 6500 but will hesitate at 5100 rpm most of the time.
Someone said something about a air filter problem??
Not really sure I believe that could be it but who knows.
I race Super Stock Race cars and work on cars for a living so I do know how to test this car in all driving modes.Just starting to get into any info anyone has on this.
I have tested in all driving modes it does the same thing it just cuts the car off at different rpm's.
Didn't get to third gear yet..

Do you have the traction control nanny on or off?

Probably to hear the supercharger whine a bit more.

The S4 guys I used to hang out with had intakes (Roc-Euro was the one they used) and you could hear the supercharger so much more with those on vs. stock.

As far as the problem a few people seem to be experiencing, it would make sense that resetting ECU adaptations might help. It's the first I've heard of a hard RPM cutoff vs. the normal timing/fuel/etc. adjustments, but it's plausible.

One "trick" I used to use in my old car running E85 was to reset the DME after I made the octane switch, as it would adapt to the change much faster. Otherwise, I'd go through 1/4 tank before I saw a whole lot of benefit.

Here is an offer, if you want me to go for a ride with you and scan it I will more than likely be able to tell what is happening. I see your location is listed as peoria, az so if you still live there it's not terribly far from Tempe and you could just meet up with me when I'm down at the dyno.

Update from the dealer...
They can not duplicate the problem no codes and no problems found.
I am going there after work to take them for a ride of their life!!!..lol
I know how to get it to do it with no problems..
I hope my friend at the dealer brought clean shorts..HAHAHA..
Just kidding you don't really have to drive this car very hard to get it to do it.
It's just like you were doing a quarter mile run take off in first gear floor it and it may do it in first gear and maybe not ,shift into second gear floor it and bam it will 90% of the time cut out at 5200 rpm or just flutters like missing on cylinders and I let off at that point.
I don't drive like this at all but when you do you want to be able to run through the gears without cutting out.

If it's the rev limiter observation I mentioned, all you have to do is begin to downshift but never release the clutch. I usually do this approaching a stop. I don't downshift in to first from second, I just shift down in to first and coast with the clutch depressed and it will usually "blip" up as if it was expecting me to release the clutch.

[dcosta]

My Friend at Chevrolet who is working on the car has captured the cutting out and has sent all the data to GM,now we wait to see what they would like him to do.

[dcosta]

Just heard back from Chevrolet they are ordering a updated air filter but we already know this is not the fix but we have to go through the motions for GM at this point.
We had tried a K&N and same results..
Picking up until filter comes in.
