naz,
I'm pretty sure the vortech unit is best-guessing the fuel.... While I know the kit has been tested, and it works fine for everyone else, there's a level of detail I'd rather have with a balanced tune. The ford ecu is smart... smart enough to keep the engine safe so long as it knows all the variables. But when you take away it's ability to directly assess certain information (ie, proper MAF readings), it begins to add an element of risk.
Hence the reason why it's a very good idea to head to the dyno to check this stuff out. Until I hit a dyno, this is all speculation tho..
I think you're definitely on the right track about the MAF. We know we can't change the ECU limit, but I was sort of hoping that the MAF is capable of more, and that it just can't be read. But if it's measuring the amount of energy needed to keep the wire hot, there would be physical limitations to the stock sensor.
Which means that recalibration would most likely require sensor replacement (different thermal properties at give voltages or exposed surface area)...hence the expensive price.
I started a thread over here to get the discussion going, but I may post it on Modular Depot tomorrow...
Anyways, that's the last of the MAF in this thread for me. . I'll start another topic as findings progress (could make a nice little tech article)...
