Yeah man, like everyone else has said in one form or another, its all about the tune. The worlds best EMS is only as good or bad as the tune. However in my VERY humble opinion the SAFC is only good if you're going to be street tuning it yourself and they never seem to make as much torque as a flash and mounting it is an extra solution to be created as oposed to an ecu flash or tune. The SAFC has nothing in it that the ecu cant control. I used to have one and it worked great but just left a bit to be desired. I'd say start out with a couple flashes (mail-in or custom tuned) and if you start doing more and more upgrades to the point where you just need more, then look for an EMS of some sort. Just my .02 and looking back i wish i would've followed this path.
ok how many people remove MAS and No2 ok not going to run. 3D maps can get that with 3rd party apps for utec not a big deal anyhow. and boost stage i dont know anything about. and im not saying AEM is bad. im just saying for a say 11sec car and making nice power it can be done with utec. but for for a 9sec car would you say need AEM. in my mind i think it can be done with utec. as anyone tryed? maybe need a post on who with a utec what most power and time get out of it. and with a AEM what you get.

the AEM also has a ton of more options to it....No2, 3D maps, boost stages....etc.
one can go on and on why the AEM is superior to a Utec....but the one thing that stands out the most...............the AEM removes the MAS...the Utec does not

and i am not saying Utec is bad either....and yes...it is possible to run 11's with a Utec. what i am saying is that the AEM system is a better system to use with more capability and options for tuning....
man this sucks its all about how you want to run. what kind of car you building. what nolege you have on tuning.

To be quite honest, I really haven't heard many good things with the Evo and UTec. Granted, I haven't heard much at all. Regardless of my deaf ears I'm sure its great and its possibly just a question of publicity but it would seem more likely to get a good tuner with lots of evo experience on other systems. It seems like the suby crowd and their tuners are more used to the Utec and its responses on subaru based platforms. I'm sure there are guys out there who could do it, but they spend so much time on other systems on evos it would make more sense to me to get whatever the tuners in your area are better suited for. If one tuner could make xxx power maxing out a safe tune on an AEM or Motec because they spend all their time tuning cars with those systems, it would make more sense to get one of those because they are more well versed on the evo with those sytems as oposed to Utec or something like hydra where its not very common.
to my understanding i thought the utec was made for the evo. and i dont think it matters to what the tunrer is good with. they see numbers and what not. they dont see o this is a nice app i can get around it. not at all. tunrer is a tunrer. they look at numbers and what does what. so that i wont agree with you. yes they need to know how the app is layed out where stuff is. but other then that i dont see. and why you say you dont hear anything good with utec there is more post for the utec then the AEM. maybe thats becasue utec more truble lol. and maybe AEM more easy to tunr. but i see most people bring AEM to people and if you want to be hardcore i say do it your self and see what you can do. and if this is all what you saying utec no good im determin to make the fastest most powerful utec run evo.

Well, agree to disagree I guess. But I will say different systems modify things in vastly different ways, otherwise AEM wouldn't be giving certification tests on how to tune with their system. And I believe the Utec was around before the Evos hit the US, the utec may have been used in UK or over seas but I honeslt couldn't tell you if you're correct or not, you probably are though since i suck at life. As far as powerful systems with the Utec, you can do it if you have enough patience and time but don't do it because you're trying to prove a point, its more trouble than its worth IMO.
its totaly worth doing it. i will push the utec till i want to add somthing to the car that needs i mean needs the AEM. and for a sleeper car i dont think there will be much anyhow. and for a daily driven car i would think utec little more realible. becasue can always use the stock ecu. but we shall see. still the post does not answer the question which is the funny. part. every one has there own thoughts and the guy who post this thread will just have to get one he thinks is for him and what he wants done and try it out. thats all i have to say about that. and off topic. im a hot sexy ladys man. tell your hot sisters that.

no...no hot sisters for you...they're all married...i'm just curious how old you are.
hehe thanks. and i em having hard time going from AEM and utec. but i think for a start off i will go with utec and see if i can push 500WHP with it. and if want more then i will do AEM or when or if i do say a GT turbo. thats down the road like year or so. and friend is very good at tunring utec. me telling him what i feel. and then he can look at log and see what im saying and change here and there. and we good to go. all street turned and let me tell you we took it on the dyno and was just about perficte. only change made like 1000rpm little smoother but thats all. i think he just scared away from AEM becasue that for big drag cars. lol anyhow i will let you all know what happen. and when i blow my evo up or somthing haha. fun fun.

For me it came down to a couple of things. One, I didn't want a full stand-alone system. If something goes bad, you're SOL. I chose a piggyback. I can always limp somewhere on the stock ECU. Also geography was a concern. I'm near Shiv. This whole new SMART thing is just an added bonus. If I lived somewhere else besides LA, I may have gone another route.
