Hi all,

I did a Stock Tune Backup before applying the Performance Tune on my 2007 Cadillac Escalade via U7194 with release 8r06 .

Before Restoring the Stock Tune, I updated the U7194 with release 8r07 .

Now I get the following message on the U7194 LCD:

Custom Tune problem: z error
dsd version ...

Thanks to mikel & 06MonteSS...

I have installed the Predator U7194 Performance Tune on my 07 Cadillac Escalade ...

Then I have replaced the stock air filter, mainfold, and exhaust with:

- K&N 63 Series AirCharger High-Flow Intake Kit.
- Gibson Ceramic Coated Headers.
- Gibson Stainless Steel Extreme Dual Exhaust.

Can you ...
