The reason for the high volume in tank pump is to eliminate the need for two. the pump being in the tank keeps it cooler and eliminates the need for extra wires/ hoses. Neil correct me if im wrong but the boost-it system will work on any application where an extra set of injectors is present. your fuel pressure and fuel pressure regulator will remain the same as before, assuming your a 1:1 with an initial pressure somewhere in the neighborhood of 38-44lbs. the boost-it box will simply tie into your extra injectors leaving the stock harness hooked up to the stock injectors.
In short, your previous turbo fuel system should work just fine with the boost-it box.
hope this helps

Yes that pretty much sums it up.
I have to admit that I am not familiar with what the 2stroke sleds were running for fuel pumps prior to last season, but I know the stock in tank pumps on all of the 2012 two strokes seem to work fine up to at least 12-14 lbs boost with extra injectors.
This is a guess, but rising rate regulators and aftermarket pumps were used to try and squeeze enough fuel out of stock injectors in order to fill fuel requirements.
With extra injectors, it is much easier to supply ample amounts of fuel for higher boost levels.
One of the reasons that the XiC works so well, is that the stock system is left alone to do what it does, and it does the same thing every time. We only add the fuel needed for the boost that the customer wants to run.
We can actually build a map for any motor/turbo/fuel delivery configuration, but it is easier for us to send out a preset map for a common configuration of injector size, fuel pressure, etc.
If the customer has a good understanding of the xic functions, then tuning is very simple and is done right on the controller. Because we do not tune oem injectors, it is simple.
The oems have spent countless hours of tuning for these motors, so why go in and mess around with it, when you can add just the fuel needed for boost.
