Well, the truck is finally running; time to start tuning the engine.

I'm running a pair of AVSs on an M1 tunnel ram; am pretty familiar w/ how to go about tuning the AFB. But I've never played with the adjustable secondaries on an AVS before, especially trying to get a pair set the same.

FWIW, the engine is a 383 with 'OOTB 'Source heads, 4.25" crank, a solid roller (262 deg @ .050), and the truck runs 4.10's with a moderate (~4000-ish) convertor.

Any suggestions how you guys go about dialing 'em in are appreciated, because you only get so many runs in a day...
