Why change it? Those numbers are fine in the condition you mentioned.

Here is a link to the instructions. http://www.turbotweak.com/sd2instructions11.pdf

The spark advance you are seeing is normal though.

Regards,
Eric

OP sounds like a V8 guy, especially with the LQ9 in his profile.

He is probably used to about 22* at idle and seeing 34* at about 2800-RPM...

Sorry for the double post, way too many ads on this website to load properly.
