Fine Tuning a 360 Magnum with a Brawler "Double Pumper"

Okay small tinkering update.

I put in smaller IABs just to see what the affect would be. (.070” to .067”). Idle screws are now about 7/8 of a turn out, I got there by starting at 1 turn out on all 4, then slowly turning one by one until it started to idle down, and backed it off a quarter turn. I did a quarter because it was unusually hot today, so wanted to give it a cushion.

Idle is nice and stable, cruise is nice and stable, vacuum is rock solid it only moves when my foot moves on the throttle. AFR gauge stays within a 0.5 deviation. Off idle is very strong, turning from a stop feels like the truck wants to light up the tires with barely any throttle. I do however have yet another question now lol.

It seems like pairing a .028” IFR with a .067” IAB has made the engine idle very happy and smooth, as well as cruise. Given this scenario, if I wanted to lean out the cruise (it’s a bit richer than before), should I put in smaller TSRs because the engine likes the smaller IAB? I know a larger IAB would lean out the transition, but it would also lean out the idle and change the ratio, which I would guess I don’t want to change because the engine is very strong where it sits right now
