AVS2 carb tuning. Anyone with experience out there?

Everybody wants their 4bbls to open ASAP, but I think you are trying too hard.

The thing is the primaries are good to something like 3000 at 100% VE, say 3800@80%.
So all that happens when you open them too soon is the airspeed falls into the basement and you get a bog.
Don't be shy to slow the secondaries down.

If you cover the bog with pumpshot, you just end up sucking the tank dry, cuz every time you tickle the gas pedal, you are shooting gas down the holes.
Same for the M-rods; delay the secondaries, and then you can dry up and slow down the power-pistons, for a cleaner PT (Part Throttle) drive, and better fuel economy.

If you want the secondaries to kick in faster, get a double pumper, and have fun spinning the tires.

nice cam;makes great cylinder pressure. Should make a nice streeter after the tune is in.
