Need more info on a ems piggyback or full standalone Options

Ok I still dont under stand everything about a ems. 1st of all its a 2nd gen 3sgte ina gt. Well I want a bigger turbo and injectors an made a post for info on it and everyone says I need somthing to control the air fuel ect meaning a ems. So I wanted a safc2 since it was cheap and was told its not what I need and It messes with timeing and other things. So I was told get a ems. These are the 3 choices I have ats rom tuned with a ct27, some type of full stand alone<very expensive> and a piggy back. The piggy back I am looking at is the greddy emanage which is $400 and a emanage ultimate which is $650 and seems to have a lot of things it can do. But is a emanage piggyback going to do the same a the safc would do and mess with my timing and not do what I need it to do with a bigger turbo and injectors? Can I control one of those ems turbo kits for 1800 with a emanage setup? Cause I dont think a ct27 is enough for what I want

i have researched this for hours upon hours for a 2nd gen... DO NOT get a greddy... i could start to list the issues with it but i already have a post about it as well... look over on mr2oc.com... search for greddy e-manage and you can begin to see why... it is not made for a 2nd gen... it cannot control ignition... greddy is going bankrupt... ZERO tech support... blah blah blah... the greddy is made for the 3rd gen 3sgte... different style ignition... ats rom tuned is GREAT as long as you use the setup they have it tuned for... DO NOT think that oh its close enough to my setup, it will be ok... it will not be ok... oh... and the $1800 EMS turbo kits are direct bolt on.. they will work with stock injectors and fuel pump... tuning is not needed ... however this all becomes pretty crappy cause you're going to run into the problems i had... the MAF sensor is a POS.... so you have two options if you want a bigger turbo to run well... standalone EMS (cough cough AEM)... i did the research... saved the money.. bought the RIGHT product... or 3rd gen electronics swap... ~$700... allows you to run MAP sensor... bigger injectors... more aggressive maps... this may be the route you want to take
