N/A Build !!

[Gabwone]

Hello guys im new on yarisworld but had my echo for a year now ... I would like to build an n/a 1nz-fe high powered close to 180hp ... I got pretty much all the bolt on for it right now c.a.i , headers, exhaust + Borla catback , koni yellow shocks on apex springs lowered 2'' with enkei rpf1 15''.... starting i would like to know what kind of management system should I use. I have seen a couple but wich one are good or bad and i would like to be able to use my power lock as well ( my only option :P ) so what i've seen so far :
-AEM EMS 4 (race car application so no pwr lock I think )
-AEM EMS 2 this look to be pretty good
-Greddy Emanage Ultimate look good but piggy back (any difference between piggy and full management ??)
-Link G4 Atom looks good too
This is what i got until now ... so any help or suggestion will be appreciated
Thank you
