dual power adder stumble
I have a dual 1200 power adder sys with the hyper fuel, the only issue I have is when you press the accelerator to where the secondary's open the moto just seams like it stops them all of sudden it just screams and takes off, I am running a 871 blower my msd runs all the ignition and timing, there is a 3 step in play
Log the issue and take a look at the log. It's probably either going lean then rich (need more accelerator fuel) or rich then lean (need less accelerator fuel).
I would like to see the trim values and AFR during this issue. You may want to learn how to adjust the cam tables to dial in the tune.
my afr seems steady, engine is very responsive, this takes place from a cruse rpm of 2200 I hit it 🙂 I receive 1 small pop out thethrottle bodied (that happend 1 time) then it all goes quite for about a second then whooooom in like a lion

As you watch your AFR during that event, it will tell you the issue. Lean then quick to Rich, not enough fuel. Rich then quick to lean, too much fuel.
what would I adjust to change the transition fuel

I adjust 2 things first. First I lean out my target AFR. Second I turn off the learn and clear the learn. Data Log some driving and begin to alter the values of the cam tables to achieve +/- 10% trim at all Data points. This will take a few drives or more to get dialed in. At that point you can turn the learn back on and drive some more to allow some fine tuning. At that point your bogging may sort itself out.
