Ignition timing discrepancy

[calvin87]

Had my car on the dyno today and the first several pulls powerlogger Spk Cmnd read 18.3 Advance 18.6. The last several pulls Spk Cmnd 18.3 Advance 22.3. I believe spark advance did increase cause horsepower did go up about 20. Translator pro was set at 18 the whole time, what could have changed? I don't like the idea of spark advance moving on me.

Third gear only pulls. I only logged powerlogger. I`ll try and post it tomorrow.
