[Dangerous Doug]

I have my side pipes off for their annual freshen-up painting. I'm thinking of having some bungs welded on so I can use air/fuel mixture sensors (I think this is actually an O2 sensor) to tune my Holley.

I would have them welded onto the inside (meaning toward the transmission) so as not to deface my pipes, just down from the collector (I have a 289 FIA, so my pipes are different than most of you.).

Anyone out there doing this? Are you using a guage in the vehicle or a handheld meter? If so, what products do you use?

I've read very little on the subject and am just getting into researching it. But, it sounds like a pretty cool hi-tech way to quickly learn how to properly tune a Holley, and keep it tuned---not to mention the ability to tune for altitude.

Anyone?
