why not replace your ls6 with a fast92/92? seems like thats your biggest restriction.. stock maf is fine past 500 horses, are you surpasing that?

i think should be in the450- 475 range,patriot stage3 heads, 236-242 duration, 650 lift with my gold roller rokers 1.85, pacesetter cer. headers and off road y and loudmouth, racetronix fuel pump, 42lb inj, not going with fast(price) at least not this year. slp lide, holley air filter, smooth below, ported tb , just looking at maf and that big alum. bar going across the center seems to not leave mutch room for air. what maf do you guys get a good perf. from.

The 85mm truck MAF would be all you would need.
