Default Need Info about ProECM

I've realise that ProECM is a self learning piggy back device for the subaru but whats the different between ProECM and unichip??

Is it right that unichip needs to dyno tune???? and ProECM dont right???

since I have done no mod on my car at the moment if get the ProECM does it mean that when I get things like exhaust and intake the ProECM will adjust it self for my car????

is it possible to use unichip and ProECM together????

Would a unichip give me more power then a ProECM chip???

Sorry PPL~ I ask too many questions but im kinda lost with this ProECM chip~~~

I don't know about the torque chip, but...

I installed the PRO ecm tonight.
Just got back from an hour drive up Interstate 5 and back. I don't really notice much of a torque increase, just a little. But the throttle response is way better. Need less throttle than before to get the same acceleration, and it revs faster alright. The exhaust sound is supprisingly better- it sounds meaner than before. It sounds like it's a bigger motor, actually. Hopefully more driving will squeeze more out of the ECU. Overall I'm real happy with it so far!

Other engine mods:
Intake & K&N
Borla Header wrapped in ThermoTec
A'pexi N1 muffler
Magnecor ignition wires
Torquemaster spark plugs
#3 fuel bypass
