Original backup of the new software is attached. Let me know if you need further info. Thank you for the assistance.

Apparently mine must still read differently. Tried that one (9t30q) and got the same unrecognized configuration error. I'll upload a copy of my backup tonight and post it to this thread.

I just noticed the post below which somebody had exactly the same problem with a 2012 and 9t30 was posted... I'm guessing I can use the same one that was posted for him?

I have a u7194 with 9r29 which I use with my '09 Sierra with the 6.2. I recently went in for some service work and they reflashed my ECM and the configuration is no longer recognized. Is there a new tune to support the new ECM software from GM that's more recent than 9r29?

Thanks.

Just an update that I am still looking at this. I decided to try fuel from a different station. I found out that the 93 octane BP is 10% ethanol even though its not displayed below the octane sticker on the pump. They recently added the 10% stickers to the pumps and now I'm concerned its the fuel. I ...

Still using BP 93. I learned quickly which gas would and wouldn't work after I got the programmer for the avalanche and BP always seemed like the best option. After I had the first "issue" i tried BP 93 octane from another station just to be sure and had the same result 2 tanks later. I had hoped it ...

Another note on the running rich issue. The truck should have only been average temp or lower. I know i was about 210 on the gauge when i started the tests all 4 times, however, our outside air temp is about 40 degrees today so I'd assume it would be running a little cooler than average.

Thanks for the quick response. I put only a few miles on between tunes so... unfortunately maybe they are invalid results due to that fact?

However, whatever the noise is, its distinct and only when the performance tune is on... best I've been able to describe it (and somebody else who rode iwth me ...

Got it. I grabbed 4 of them...

Stock - Normal Cruising
Stock - WOT

Performance Tune - Normal Cruising
Performance Tune - WOT

I've attached them to this post in a zip file. Let me know if you need anything further. The stock results at WOT even look odd to me but... I'm not sure how much it is ...

I have a 2007 Yukon Denali with 59k miles that I just purchased a Predator u9174 for. When I first got the tuner it was running 9r09. I put the performance tune on while running my usual 93 octane BP gas. I definitely noticed the torque increase right off the bat, however, I also noticed some ...
