On this page I intend to list all of the C&L sample tubes (by color code) and their respective diameters. For the official and current application chart from C&L check here...
http://www.cnlperformance.com/calibration.html
With this info you should be able to figure out what sample tube you have, even if the color coding has been removed. Also, if you are not using an aftermarket tuner, you may be able to select a tube that will allow you to move slightly leaner or richer, if you desire.
Several of the following diameters were contributed by Cougar5.0 of EECTuning. Check out this thread he started...

The following dimensions should be taken as apporximate, as measuring devices vary in their accuracy.
If you have a diameter measurement to contribute please contact me at my email address, listed at the bottom of the page.
