Horsepower Calculation Change
The 04 TL is rated at 270hp and 238tq, and the 07 which I have is rated at 258hp and 233tq. I've read that this change is because Acura changed the way that they measure these numbers in 2007 and that the two cars have the exact same engine/power. Is the 04 TL slower than advertised or is the 07 faster than advertised? Doss anyone know more on what actuly changed and what the true power is?

It wasn't Acura specifically that changed the way that horsepower is measured. The auto industry altogether did. So that goes for all makes and models. It was 2007 that the new horsepower ratings were put in place.
The 04-06 and 07-08 base model TLs both share the exact same 3.2L motor and make the exact same power and torque. So no, the 04 TL isn't any slower than advertised and the 07 isn't any faster than advertised. They are identical.
The only thing that changed was the method used for getting HP ratings.

Which means if the Type S was rated using the same methods as the older 04-06, then it would have over 300hp ;-) Which from my understanding is what the same 3.5 was rated at in the RL of the 04-06ish range.
Sorry that was completely off topic, but just had me thinking.

he first third-generation Acura TL rolled off the assembly line on September 30, 2003. On October 6, 2003, the third generation Acura TL (the 3.2 moniker was dropped) was released for sale in North America. Developed mainly in the United States by a team led by Erik Berkman with bodywork by American Honda designer Jon Ikeda, the new TL was built in Marysville, Ohio, and was derived from the 7th generation US-market Honda Accord.
Starting with this generation, this model was not sold in Japan, with the Honda Inspire holding the position of entry level luxury sedan below the Honda Legend in Japan. The Inspire of this era was instead sold as the seventh generation North American spec Honda Accord.
It is powered by a 270 hp (201 kW); later revised to 258 hp (192 kW), based on the new SAE measurement standard for horsepower and 233 lb·ft (316 N·m) of torque, 3.2 L 24 valve SOHC VTEC V6 engine mated to either a 5-speed automatic with SportShift or 6-speed manual. Manual transmission models featured Brembo 4-Piston front brake calipers, a Torsen-type limited slip differential, stiffer anti-roll bars front and rear and performance tires at no additional cost.
As of March 2004, Honda offers to the public a factory-sanctioned "tuner package" version of the TL called the TL A-SPEC. This version features a suspension tuned by Makoto Tamamura, an indication of the TL A-SPEC's aggressive engineering. In addition, an underbody kit, spoiler, limited edition A-SPEC steering wheel, "A-SPEC" badge on the back, and 18-inch (460 mm) wheels are standard issue on the A-SPEC package. When installed at purchase, the car's 4 year/ 50,000 miles (80,000 km) warranty applies to the package as well.
The third generation TL was also the first car in the American market to include a 6-disc DVD-Audio system, output through an 8-speaker 225-watt system, engineered by Panasonic and tuned by Grammy-award winning Elliot Scheiner. The system also plays back regular audio CDs as well as DTS audio discs, CD-Audio, CD-Rs and CD-RWs but not MP3s. In the United States, all models were also equipped with a Bluetooth HandsFree Link (HFL) system, integrated with the audio system, to allow for hands-free usage of one's cell phone (provided the phone also supports Bluetooth and is compatible with the HFL's hands-free profile). In Canada, the HFL feature was not available on the base model (standard with A-Spec, Technology, and Navigation packages), though the 2005 model year saw HFL becoming standard in all Canadian models. With the built-in XM Radio tuner, owners can elect to pay a monthly subscription after the complimentary 3 months subscription expires from Acura for XM radio, which provides over 100 digital channels via satellite.
Sporting an Alpine-designed navigation system, the third generation TL also accepts voice commands[7] like "find nearest police station" or "go home." The navigation system features an 8-inch (200 mm) touchscreen LCD, which allows for easy viewing of the road ahead.
The JDM Honda Inspire debuted around four and a half months earlier (on June 11, 2003) and marked the branching out of the TL line from the Inspire. The Inspire is basically a seventh-generation US-market Honda Accord V6 with minor trim changes, and the addition of Variable Cylinder Management, which shuts off half of the engine when not needed to boost fuel economy. The Saber was discontinued and the new Inspire is being sold at Clio, Primo, and Verno dealerships.
The TL became Acura's best-selling luxury sedan in 2004 with more than 79,000 sold that year.[8][9]
The IIHS found the Acura TL had the second lowest fatality rates among midsize luxury cars.[10]
2005
The 2005 TL received a passenger airbag cut-off switch and indicator and extra stitching on the front seats. There were several minor changes made (such as changes in seat belt anchor mounts) which are not published.
2006 TL A-SPEC
2006
The 2006 TL received the Tire Pressure Monitoring System (TPMS) and a new engine management system to help reduce torque steer. The new horsepower rating of 258 hp (192 kW) is due to a change in testing procedures, despite the engine remaining the same since 2004.
2007
The 2007 Acura TL features a slightly revised exterior as well as a revised interior with a new steering wheel, redesigned gauges, and footwell lighting, in addition to new interior and exterior colors. The 2007 TL (non Type-S) received suspension changes to improve ride comfort. Also new for the 2007 model year were LED turn signal repeaters on the side mirrors and fog lamps in the bumper. Prior to 2007, the fog lamps were integrated into the headlight housing; Daytime Running Lights now occupy that space (Canadian models have had DRLs there rather than fog lamps since 2004).
TL with navigation models sport a new rear view camera with image displayed on the navigation screen as well as XM NavTraffic. In addition to the new standard auxiliary audio jack, the sound system is now MP3/WMA compatible and offers Dolby Pro Logic II decoding and speed-sensitive volume compensation. The manual transmission option had been dropped from the base TL due largely to extremely low sales (roughly 1 out of 40 TLs sold across America were equipped with a manual gearbox).
The most notable revision is the return of the Type-S edition of the TL. The Acura TL Type-S received the Acura RL's 3.5-liter V6 tuned to 286 horsepower (213 kW) with either a 5-speed automatic with F1 style paddle shifters or a 6-speed manual transmission. The Manual transmission includes a Limited Slip Differential. Exterior differences include quad exhaust pipes, restyled rear lamps and front fascia, lip spoiler, wider side sills, Brembo brakes, dark silver 10-spoke wheels, a "black chrome" grille rather than the standard glossy grille, and exclusive Type-S badging, plus an exclusive new color option, Kinetic Blue Pearl. The interior has Type-S badging on the steering wheel and headrests, more highly bolstered front seats, two-tone seats (only with the Ebony/Silver interior), metal racing pedals, carbon fiber trim, and red interior lighting (as opposed to blue in the base TL). Touch screen navigation is standard and the suspension has been firmed up. The only options are the aforementioned transmission and high performance summer tires (Bridgestone Potenzas) rather than the standard all-season tires (Michelin Pilot MXM4s).
