just as an fyi - if you were interested - all impco lpg gear is made to be able to be run in a blowthrough right from the getgo, you just need to run a balance pipe from the convertor front plate to the mixer before the air valve. this gets pre mixer boost pressure to the convertor and ramps up it's output. They are generally ok up to around 10psi boost, some go up to 15, but you might find the convertor start to leak just a little on the outer plate/cover at those pressures.
