So, you’re using the on board Map sensor, which is only good for 15psi, but running at 21?
Have you hooked a laptop up to the car to see what the engine parameters are doing? What does your timing do when it drops to 10afr? There is a plethora of information you can obtain from a laptop and the Haltech. I suggest you datalog when the car is running and contact your tuner with the files. My guess is timing and fuel enrichment maps are off, based on engine temp. This is just a stab though.
