Default wierd ignition problem...

alright so lets start out there is NO codes BOTH knock sensors are brand new and the cps works perfect
basically the ecu is overcorrecting everything at idle with a 10btdc baseline (pins jumped) it runs around 15btdc corrected and when it starts to come on boost it hits about 5psi and just drops out won't rev and starts to sound like its missing because it pulls so much timing out of it (I replaced the plugs with autolite copper gapped to .030") if i advance my baseline to 15btdc it idles at ~20-22btdc but it will run up into boost just fine atleast up to about 5krpm if i run just a little more then it would probably pull fine all the way to redline.
the only problem with this is that when its idling with that much correction it misses HORRIBLY there is no pinging and the engine is mildly built 550cc injectors maf-t blowthrough nice intercooler forged pistons titan mhg and arp studs it has 1400 miles on the rebuild and has been running perfect until yesterday.
i read somewhere that possibly my balancer pulley has spun is there any factory marks I could look to see if it has spun or not?

The only way to verify the harmonic balancer is at 0? is to put a dowel or chopstick or whatever you like in the #1 spark plug hole and rotat the crank until it stops rising... That'll show you where TDC is for cylinder #1 is.
