something I was curious about regarding the Xcal three and a timing adjuster.
 

Like the title says my car has both and I was wondering if having the timing bumped with the adjuster and im guessing having the Xcal add timing am I in danger of blowing up? Are they both working in conjunction and jiving together, are they both adding timing equaling too much or will the ecu compensate and retard it or what? This occured to me earlier tonight and the thought of it kinda freaked me out.

And what would be a good safe but aggresive degree of timing at WOT running 91?

You need to remove your timing adjuster, or set it at 0. But its completely pointless to leave it on there.

So should I set the adjuster at 10 degrees which would be stock timing or set the adjuster to the 0 mark? And again what would be a safe but aggresive degree of timing at WOT on 91?

You should take it off and sell it. Timing adjustor's are crap. They set your timing at that given degree no matter what RPM. It isnt adjusted based on RPM like it is when you adjust it in the tune.
