we never got to find out. he had to move/transfer (navy) but the 72lbhr injectors are at 95% duty cycle.

That's amazing, what is that bad boy making to the wheels? At least 300hp.

that's a buddies truck that him and i built. the motor has eagle rods, forged pistons, comp 224/224525/525 110lsa cam. heads are P/P'd by a local guy with comp 918 springs. we put on a set of syty manifolds and a mpt70 turbo blowing through a marine intake manifold fuel by 60lbhr injectors. they flow like 72lbhr with our pressure and they are almost maxed out.

Is that your truck? What all is done to the 4.3?
