Sounds like a fuel cut off from protection. Check all of your parameters!!! Im assuming you have a wideband?? the provided calibrations need to be tailored to your setup!!!! Check lean Protections!!! SUCH Nice feature!!!!!! I didn't use them until I cracked welds on manifold!!! not sure if was lean situation or just cheap manifold!!! but im back in action and using them=) PEACE OF MIND!!!!

stock injectors is your problem here is a b16 tune I made. Stock injectors max out in vtec at 3.8lbs at 5k rpm around that point.

You can't run stock injectors with boost!! Look out so you don't throw away your motor...

Stock the injectors are at 100% duty and there's just the fuel pressure that's difference so you really don't have much to play with and especially no boost!!
