Pulleys, shifter,and gears oh my!

[michaelgta]

I am wanting to do the shifter, pulleys and gears on my new 2005 gt. I did all this and more on my 2000 and 2003 gt. I know I will have to calibrate my speedo for the gears. Will I have to tune my car for the pulleys?

A tune is not required for pulleys, but you will need one to recalibrate the speedometer for a differential upgrade.

I have seen quite a few threads about pullies, what is the specific advantage?

the pulleys under drive the accessories to free up extra horsepower.....

I appreciate the reply. I have used the pulleys twice and was very pleased with the results. Steeda has been my choice and was allways good quality. I just do not want to mess up my 2005 with this new computer.
