TexasJim and I got together today to re-test his 2006 Cadillac DTS Performance Sedan. TexasJim has had it tuned with EFILive.
Texas Jim's 06 DTS and Bruce's 05 CTS
We used a Race Technology AP-22 performance meter (other AP-22 Tests) for the acceleration testing, a CruiseCam headrest camera mount and Kodak C875 Digital Camera for the chase-car video and photos.

Here was the previous test, with only the best run captured in detail.

The other recorded run from Test 1 was 0-60 in 7.2 sec. Using 4,330 lbs, the AP-22 calculated hp at the wheels on run 2 of 238hp, and run 3 of 241hp. Average whp = 239 whp; 239/0.8 = 299 net hp.

Conclusion: TexasJim’s DTS previously ran 0-60 in 6.68-7.2 seconds. For the 2nd test (today) it ran 0-60 in 6.55 sec – 6.67 sec. This appears to be an improvement in 0-60 time on average. Measured wheel horsepower increased from 239 whp average to 268 whp average, or 29 whp. Having the DTS performance tuned yields positive results.
