That is funny because I found a decent amount of power by advancing the MIVEC at 6500 and 7000.

It was a derivative of this map:

Dan I,
One thing that I noticed from the logs you posted is that you have started each log at a different RPM. This can throw off your results (especially at low RPMs) because of the turbo having different transient response characteristics when you start the pull at different RPMs.
Not trying to knock any of your work, I think that this is the best method to possibly tune the mivec timing.

I just tried the 4.8 advancement and called it a day. This car was doing 294whp on a low-reading mustang dyno that read likes buschurs.

That brings up a question... Does the Mivec Map then default to 0 if your RPM is above your highest break point?

This has been covered, and on a real dyno, not a virtual one...

More info is good info though. I just think its easier to see what is "actually" happening on a dyno.

If you have to go much more than 30* you need to rethink camshaft strategy. Subaru does it too give as much early torque as possible and maintain emissions. Between TGV's, AVCS, a small turbo, and a bigger motor you'd think they would be able to do it right to begin with. I like Subaru, but come on guys plan correctly and avoid some issues.
IXs with MIVEC and stock cams can move peak torque (not just boost, BUT peak torque) down to 3150 or so with proper tuning. I cant wait till I get some time and a little more money to throw in an intake cam.
