Why does my car untune itself after a couple days?
It idles fine after loading the tune...but gets progressively worse (hunting up and down from 600 to 1300 rpm).
What can I do to make the tune stick?

Mods include heads/tsp 225 cam on 112LSA, M6, pulley, lid, etc.
---Stock exhaust system---
I have multiplied the VE table in the first 3 cols by 60, 80, and 90 roughly, among other tuning. It idles beautifully for about 2-3 days, then goes back to hunting.

I have noticed on several forums that most of the time you don't help people out with their questions, but instead just fix there files. That is great and all, but for us that want to learn, it sucks. JMO.
