I like what Goran is saying and that would probably be a better approach.

However, there are not chips that I know of that would support doing this. It would require enlisting someone to develop a proper chip to do this or a piggy back computer. This would require a fair investment.

One of the advantages to the Protomotove approach is that the RRFRP is not only is there proven chips available but it is somewhat self adjusting for different levels of boost. If boost increases, more fuel. If it decreases, less fuel.

If one wanted to they could do a MAF conversion and possibly tune around new injectors using the MAF to AFM adopter box to fine tune AFR's. Would still need some help with a chip on the timing side and some on the fuel side.

Even more interesting would be to attempt a MAP conversion. There is a cool box that with the adaption of a TPS might work. Some one on the 944T board seemed to have success doing so. See:FULL THROTTLE SPEED - MAF Translator PRO

Again, the Promotive approach is proven up to almost 500hp so it would take a lot less development time.
