I think we are due for some kind of update on supplemental port injection for the B58. Since there appears to be a fueling limitation in the DME currently, wouldn't it make sense to make a new plate and see what it can do? Maybe @Dave @ Fuel-It! @[email protected]! have an iron in the fire?

DME flashing really needs to be the first step. There are already reported bad shift behaviour due to the DME thinking it's running stock boost/torque. We need to the target AFR, timing, fuel scalar and torque limit tuneability at the very minimum before PI would be something to consider. Also, we need to know the real fuel pump/injector limitations (after DME tuning) so that people know at what power output and what fuel PI is required.

I was pretty sure I had read something that @[email protected] said which hinted that some progress might be possible with PI in the face of the DME issue, though I'm not sure exactly what he meant.
