I read earlier that you said that your check engine light came on, have you scanned for codes yet?
As for the acceleration issues I believe that once you replace the spark plugs you will see you that the car will start behaving better I would bite your time until you’ve done the work
Thanks again I will let you know what happens. Any idea how much $$ im looking at to change spark plugs and fuel filter; also, should i change my coil packs too or are they not related?
Yea, I wont deny it, I love flooring this car! I hope im not messing up the transmission, someone told me i should accelerate gradually to not mess up my engine or transmission, but i told him that im pretty sure the V10 can handle it.

I paid $127 incl shipping for 10 plugs - NGK PFR6WT. The fuel filter (Mann WK 720/4) was about $28 IIRC. Fuel filter is easy DIY, plugs require a little disassembly.

Guys is there any way to upload a video in here? I wanted to show you a video of my startup issue that I was mentioning, it seems as if it will start on first gear, go up to about 2 RPM and when it shifts to second gear, the RPM just keeps increasing instead of going back down and comming back up (like all cars ive previously driven). Any ideas?

Here you go:
Prerequisites:
- Ignition ON and Engine ON.
- No Fault Codes stored.
- Transmission Oil Temperature must be between 60 °C and 90 °C.
- If the procedure does not succeed in the first try, make sure the temperature is above 80 °C.
- All driving and braking has to be done in partial load, avoid full throttle/braking!
- Normally the adaptation needs to be carried out when:
- Transmission Control Module has been recoded
- Input Shaft has been replaced
- Hydraulic Unit has been replaced
- Transmission Control Module has been replaced
- Transmission has been replaced

- Move the selector lever in position D and drive with partial load 20 m / 70 ft forward, then brake to standstill.
- Hold the brake for 10 seconds.

My recommendation would be to perform an adaption on the transmission: 6-Speed Automatic Transmission (01J/Multitronic) - Ross-Tech Wiki\

The transmission adaption essentially resets your transmission and allow it to map to your driving style. Since, this is a new to you car, I'd also recommend you change the transmission fluid and filter...use the SEARCH and you'll see plenty of threads on it.

+1. Find a 1-2 mile road that has little or no traffic, and do this. I did it on my A8 with the same ZF trans and was very happy with the result. It lets the trans adapt itself to your driving style.
