I used the larger maf tube from the 987 intake and that is probably the cause. Car is going to a shop for a dyno tune today.
Why does it run very well with the maf disconnected? Does the ecu default to a baseline? Is the primary purpose of the maf to optimize fuel mix for mileage and emissions?

Yes . Without the maf it defaults to open loop/limp home mode. Some have said the open loop programming is pretty good ,but I suspect it will run overly rich .
Threaded Mode
