Here is the gearhead pages for the 1227302
http://www.gearhead-efi.com/Fuel-Inj...Information-3A and the 1227730

There is more support for the 1227730.
It might be possible to use a 2 bar MAP with either 1227302 or 1227730 to provide fuel and spark tables for boost.
It might also be worth looking at the possibilities of using S_AUJP with the 1227730

There is also the option of using a resistor inline with the fuel pump power wire, like Buick did with some of it's supercharged engines. The Buick design was to bypass the fuel pump resistor, when the engine is in boost, to supply extra fuel when the engine is in boost. With the resistor bypassed, the fuel pump would run full battery voltage. With the resistor the fuel pump would run with less than full battery voltage.
Then again, MegaSquirt is also a good option. MegaSquirt is not the option I would choose.
I would use the LS1 computer with a special operating system for boost. I would also fabricate a custom dual trigger (cam & crank) distributor for the 2.8, see attached CAD design for a V8 dual trigger distributor.
