Question best fuel management for my setup?

Im going to be headding to ATP or vishnu to get a dyno for a 02 wrx... When i dyno i will have on the car an vishnu U/P, 3" TURBO back( no cats ), IC hoses, Zerosports intake and k&n filter, lightweight crank pulley and colder plugs...

Also i have an MBC ( running 13psi )and a Dastek Unichip ( <-- i have no idea *** is does can someone explain )

I havent had time to consult with the owner of the car about what the Dastek Piggy back ECU is,

But with that said... My plans are to get a S-AFC and have it tuned to give me the fuel needed for my setup...

I don't want to get a re-flash yet because I dont know if i'll be done modding for the future, maybe get an exhaust manifold or larger turbo.

But whats your suggestions.. iM pretty much new to the suby powerplant

The Dastek Piggy back ECU, otherwise known as a unichip is a piggyback fuel and timing computer. As well as being able to make fueling changes, like a S-AFC, it is also able to make timing changes as well.

That being said, apart from the ability to tune yourself, it seems redundant to put a S-AFC on the car when you have a unichip. It would be far more worthwhile to have Vishnu just tune the unichip, a system they have lots of experience with. This will most likely give you far greater gains than the S-AFC due to the ability to make timing changes.

cheers
