Comparing Previous DTS run data

UPDATE: TexasJim notes: Yes…the shift point redline has been raised to 6800 RPM.  It now shifts to 2nd right at 55 mph and it now shifts to 3rd at 88 mph”.

Looking at how TexasJim’s 2006 DTS performed in our original Tests (Session 1) versus in our updated test after tuning (Session 2), I wanted to explore the details on the difference between the Sessions:

Session 1 Runs 1-1 to 1-3:



Power: 76.8mph 9.60s 624ft 228hp
Power: 47.8mph 5.02s 184ft 238hp
Power: 77.5mph 10.01s 661ft 241hp
Session 2 Runs 2-1 to 2-3:
Power: 55.0mph 5.73s 248ft 271hp
Power: 54.0mph 5.67s 241ft 269hp
Power: 53.9mph 5.64s 239ft 263hp

The times were not THAT different.  But by analyzing the 0-60 times it is clear that the largest margin is all the way up at 50-60 mph times, where the new tune shows a significant hp spike, and is 0.2 sec quicker:

Tuned Cadillac DTS Performance Sedan sets a new fast time

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

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.

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.

GM Reports 156,380 Deliveries in March

  • “GM Total Confidence” brings peace of mind in uncertain times with Payment Protection and Vehicle Value Protection
  • GM total sales up 23 percent compared with February as spring selling season begins
  • GM’s award-winning crossovers drive March sales as Chevrolet Traverse sales of more than 6,500 vehicles helps push GM mid-utility crossover segment sales up 10 percent compared with last March
  • Pontiac G8 sales nearly triple compared with a year ago

    DETROIT – General Motors dealers in the United States delivered 156,380 vehicles in March, down 45 percent compared with a year ago. However, comparing March sales with February, 7 of 8 GM brands saw total sales increases with total volume up 23 percent, or more than 29,000 cars, crossovers and trucks. GM’s car sales compared with February were up more than 15,000 vehicles (28 percent), truck sales were up nearly 11,000 vehicles (23 percent), and crossover sales increased more than 3,000 vehicles (12 percent) .

    “Sales for GM and the industry showed signs of life at the end of the month compared with January and February. In April, we’re stepping up to the plate to get a rally underway with ‘GM Total Confidence,’ our unprecedented customer protection package,” said Mark LaNeve, vice president, GM North America Vehicle Sales, Service and Marketing. “We are encouraged by actions taken by the Federal government to stabilize the industry and stimulate demand. As we continue the reinvention of General Motors, our brands are adding even more world-class, fuel-efficient cars and crossovers to their portfolios. We will also continue to add even more fuel economy technology to our trucks.”

    When compared with March a year ago, GM total car sales of 68,877 were off 41 percent and total truck sales (including crossovers) of 87,503 were down 47 percent.

    Compared with February, total Chevrolet sales were up 25 percent. Specifically, cars were up 28 percent, trucks were up 25 percent and crossovers increased 19 percent. Chevrolet Silverado and GMC Sierra pickups gained strength in March, when compared with February, with retail sales up 17 and 27 percent, respectfully.

    Chevrolet’s crossover portfolio of HHR, Equinox and Traverse combined for 14,844 total sales in March, a 19 percent increase compared with February. In addition, Malibu has increased retail sales for the first three months this year, with sales up 7 percent compared with the same period a year ago.

    “We had a strong close at the end of the month as customers responded to strong incentives, President Obama’s positive statements about GM, and the government backing domestic warranties,” LaNeve added. “Customers told us they wanted a manufacturer to look out for them, and that’s exactly what the ‘GM Total Confidence’ program does.”

    A total of 1,612 GM hybrid vehicles were delivered in the month, illustrating the wide range of hybrid product offerings available. GM offers the Chevrolet Malibu, Tahoe and Silverado, GMC Yukon and Sierra, Cadillac Escalade, Saturn Aura and Vue hybrids. So far, in 2009, GM has delivered 3,622 hybrid vehicles.

    GM inventories dropped compared with a year ago. At the end of March, only about 765,000 vehicles were in stock, down about 108,000 vehicles (or 12 percent) compared with last year. There were about 332,000 cars and 433,000 trucks (including crossovers) in inventory at the end of March. Inventories were reduced about 15,000 vehicles compared with February.

    Certified Used Vehicles

    The challenging economic environment had an effect on March 2009 year-over-year GM certified total sales. GM Certified Used Vehicles, Saturn Certified Pre-Owned Vehicles, Cadillac Certified Pre-Owned Vehicles, Saab Certified Pre-Owned Vehicles, and HUMMER Certified Pre-Owned Vehicles, combined sold 32,788 vehicles.

    GM Certified Used Vehicles, the industry’s top-selling certified brand, posted March sales of 28,000 vehicles, down 27 percent from March 2008. Saturn Certified Pre-Owned Vehicles sold 974 vehicles, down 6 percent.   Cadillac Certified Pre-Owned Vehicles sold 3,143 vehicles, down 5 percent.  Saab Certified Pre-Owned Vehicles sold 436 vehicles, down 16 percent. However, one brand showed strong results for the month – HUMMER Certified Pre-Owned Vehicles sold 235 vehicles, up 44 percent.

    “Although March sales were down, we’re confident more shoppers will seek the quality and value that GM certification offers,” said LaNeve. “In uncertain times, Certified Used Vehicles offer consumers the peace of mind that comes with factory backed warranties, such as the 12-month/12,000 mile bumper-to-bumper warranty, reinforcing the durability and reliability of our vehicles.”

    GM North America reports March 2009 production; Q1 2009 production reported at 372,000 vehicles; Q2 2009 production forecast remains at 550,000 vehicles

    In March, GM North America produced 170,000 vehicles (73,000 cars and 97,000 trucks). This is down 67,000 vehicles or 28 percent compared with March 2008 when the region produced 237,000 vehicles (124,000 cars and 113,000 trucks). (Production totals include joint venture production of 8,000 vehicles in March 2009 and 20,000 vehicles in March 2008.)

    The region’s 2009 first-quarter production was 372,000 vehicles (116,000 cars and 256,000 trucks), which is down about 58 percent compared with a year ago. GM North America built 885,000 vehicles (360,000 cars and 525,000 trucks) in the first-quarter of 2008.

    The region’s 2009 second-quarter production forecast remains at 550,000 vehicles (195,000 cars and 355,000 trucks), which is down about 34 percent compared with a year ago. GM North America built 834,000 vehicles (382,000 cars and 452,000 trucks) in the second-quarter of 2008.

    General Motors Corp. (NYSE: GM), one of the world’s largest automakers, was founded in 1908, and today manufactures cars and trucks in 34 countries. With its global headquarters in Detroit, GM employs 244,500 people in every major region of the world, and sells and services vehicles in some 140 countries. In 2008, GM sold 8.35 million cars and trucks globally under the following brands: Buick, Cadillac, Chevrolet, GMC, GM Daewoo, Holden, Hummer, Opel, Pontiac, Saab, Saturn, Vauxhall and Wuling. GM’s largest national market is the United States, followed by China, Brazil, the United Kingdom, Canada, Russia and Germany. GM’s OnStar subsidiary is the industry leader in vehicle safety, security and information services. More information on GM can be found at www.gm.com.

    Note: GM sales and production results are available on GM Media OnLine at http://media.gm.com/us/gm/en by clicking on News, then Sales/Production. In this press release and related comments by General Motors management, we use words like “expect,” “anticipate,” “estimate,” “forecast,” “objective,” “plan,” “goal” and similar expressions to identify forward-looking statements, representing our current judgment about possible future events. We believe these judgments are reasonable, but actual results may differ materially due to a variety of important factors. Among other items, such factors might include: our ability to comply with the requirements of our credit agreement with the U.S. Department of Treasury; the availability of funding for future loans under that credit agreement; our ability to execute the restructuring plans that we have disclosed, our ability to maintain adequate liquidity and financing sources and an appropriate level of debt; and changes in general economic conditions, market acceptance of our products; shortages of and price increases for fuel; significant changes in the competitive environment and the effect of competition on our markets, including on our pricing policies. GM’s most recent annual report on Form 10-K and quarterly report on Form 10-Q provide information about these factors, which may be revised or supplemented in future reports to the SEC on Form 10-Q or 8-K.
