Alright so, I had made a previous post about idle. Got that pretty much squared away.

Now I have a quick question about the CAS.

So I got my engine from a local importer, and had them install it. After driving it for about 2 months I showed it to a friend with an SR. He noticed that they had my CAS turned totally retard to make it idle where it should. I guess that's how they got their 15* when they timed it and handed it to me.

For shits and grins we put it in the middle where it should be. Runs fine other then if I get into boost then come to a stop. Sometimes it will rev to 1900 then dump to 12-1300 in what seems a timed loop. So obviously that's not where it's supposed to be. Leading me to think the CAS is off a tooth?

I now have it back to where they had it, and I may add this thing has no balls whatsoever now compared to when it's set in the middle.

So my question being. Engine out of time? CAS Off a tooth? Or bigger issues?

The only mods it has is a fmic, and a cheap eBay bov, and the boost guauge I have reading in bars.
