If you up the psi (mechanically of course),wWill your aftermarket controller add more fuel and timing automatically or it will stay the same as the present boost of 5.5lb?

1. If it is does:
You will not gain much from th AW system, or at worse, you lose power due to retard timing and over rich mixture.

2. If it doesn't:
You will make a reasonable gain from AW system because you wil be able to take advantage of the leaner afr and same timing as 5.5lb.

There is always a possiblity of altering the signal from the sensors to the controller. It is the next best thing to alter the actual controller's fuel and iignition tables

Question: who make the piggyback controller?
