sr20det running rich at idle. ( tried everything!)

[mt055]

alright guys here it goes.

sr20det, z32 maf, 550cc injectors, dyno tune ( chipped ecu )

My problem is my car runs extremely rich at idle...and pretty rich under boost. At idle i can see anywhere from 10-11 on my afr gauge. Under boost i've noticed it gets around 10.9 and my coilpacks and ignitor get b**** hot! ( i believe that running so rich is causing my coilpacks to use more current to blow through the mixture, thus creating more heat, causing them to overheat? ) When cruising my afr is perfect, 14.6-15.2.
The things i've replaced
-fuel pressure regulator, installed gauge also. correct pressure set
-spark plugs. one step colder. gaped to .028
-fuel filter
- ignitor/coilpacks
- O2 sensor
- replaced 02 sensor on wideband too
i've also checked my ecu for codes, flashed a 55 which means no problems. I've checked my injectors for leaks, nothing. I've taken my whole harness out twice and looked over it for shorts. its perfect. I've checked all grounds also.

Could a faulty maf be causing all of my problems without throwing a code? I should also add that after driving it for a while it starts to lose power under boost. ( because of the hot ignitor and coilpacks, i know this for sure )

I'm open to any ideas people, help me out! thanks.

faulty tune, if its good under partial throttle driving then its in the tune,

whats your fuel pressure at?

[mt055]

fuel pressure is at 43 with vac off...lower once its on. a friend of mine who tuned assures me its not the tune tho and has looked over it. its running way too rich at idle for it to be the tune.
