Maf?
do you have vag-com, if you know how to use it, hook it up and check timing is within allowable specs, no check engine light? have vag-com do a diagnostic.
Timing should be up around the green line. I don't know the hole size of the 764 injectors, but if you are running anything under .216 size the pump will not be able to push the fuel through with a stage 3 Malone.
The timing will help a bunch or shouldStill the vnt 15? Does it work properly? Sounds like it might not if you are losing some.
The factory airbox flows more air than any aftermarket CAI. That isn't your problem. If you're blowing black I'd be looking for a boost leak somewhere - intercooler pipes, etc. Sent from my XT1097 using Tapatalk
Plugged up intake would be another prime candidate! Sent from my XT1097 using Tapatalk
