Have you already settled the ECU issue of not being able to read boost on an NA ECU, or are you swapping ECUs as others have done?
Haven't had it back to the dyno running as yet, so I cannot say we have encountered that problem. Because it is a dead-head fuel system, we have gone in the direction of a boost-a-pump fuel pump controller that responds to boost.
Only when I get it running will I discover what else may be needed. There are ways to bring the MAF back into its range...
