You really can't put the vi-pic in the same class as the rest of the fuelling systems out there.
The vi-pec is a stand a lone, the rest are piggy backed off the stock ECM, also the vi-pec has full control over all the engine functions of the engine, timing, deto control, up to 6D fuelling...
I know this sounds dumb, but have you tryed a new set of spark plugs, it sound like the spark is been blowin out when the boost comes on and plug gap. Run it a little tighter on turbo motors.
