As far as i know only thing done to heaths engine is its rebuilt, moosed and turboed, now you said earlier the moose pump and dps injectors would be the way to go, wrong actually, i have some dps injectors and the really suck! they wont idle worth crap the suck fuel like crazy and smoke like mad, If you ever seen a DPS injectors pop tested you would be sick all the do is **** a stream of fuel

The moose injectors atomixe fuel beautifully and shoot an amazing amount of fuel out, the reason his power went down is the boost was so high after the moose injectors that it was super heating the air, he needs a differnt turbo thats more in its effieceint range, and even an intercooler so that it will cooler that air charge, then i bet we would really see some nice numbers, oh and his boost gauge is only a 15 PSI gauge just imagine what hes making for boost
