OK. I think I'm ready to bite the bullet and enter the 21st century. Was thinking of taking my new combo to the local chassis dyno. I'm interested in A/F ratios at idle and through the rpm range. My thoughts are that the only information that I won't receive from the wideband kit is HP and shift points. That being said, help me determine what kit to purchase.

My combo is from the stone age. 496 six pack (stock intake). The combo has headers. Will i need to weld a bung into the exhaust? How do i retrieve the information? Is the sensor connected to a laptop, or gauge.

I looked online, and it seems there are lots of options. There also seems to be a significant difference in quality and price. What are you using?
