Electramotive/Haltech/Motec Fuel Injection - Injected LPG

[Carl Summers]

Sorry to be such a pest about this,,,but does this restrict or virtually
eliminate boost at high rpms???does the intake achieve vacuum at wot
because of the restrictor...I ask this because I have been involved in a
great number of restricted carburetion engine programs and worked for a
major camshaft manufacturer,,so enquiring minds blah blah .....

In Oz, Haltech and Motec are widely available, but I came across someone selling an Electramotive TEC II system recently and have had some trouble locating some info on the system over here.  Does anyone have any good/bad/otherwise experiences with these systems.  It will be used on a Circuit track race car - RA28 'Mustang' Liftback fitted with a turbo 3S-GE engine that due to a 36mm restrictor, will produce ~ 320hp.
