Timing adjustor or chip?

chip can adjust timing for you, and lots of other things. not sure on the dual program thing for superchips.

The only real point to a T/A is to save money and self installation. A chip will allow you more options when it comes to timing and A/F ratios. With a chip you can make intermediate changes to timing and A/F as the RPM's go up. You can't do that with a bolt on T/A. I think Diablo has the only dual program chip.
