if you get a flash you do not need a safc. If you want to flash your car you need a datalogging program(Evo Scan v0.97), and obd2 port cable, and a laptop to log your car. After logging your car, you send your logs to the tuner you pick to tune your car( i recommend jestrtuning because i heard only great things about them). The tuner will then tweak your stock ecu maps with your current mods and try to get the safest setting and most power out of your car. and you live in florida which is home to jestr tuning and ttp-engineering.
or you can go the emonz way and be nasty with a s-afc and tune your car your way.

If you get a flash it is only good for your current mods... If you add any more mods after you will need a new flash if you want the most power and safest tune. So I always say if you dont want to keep paying for reflashes I would flash then buy an SAFC for the little tweaks here and there if you add any mods. A flash is far more effective and a SAFC. a Flach can turn up your boost without a boost controller and can tune timing maps as well as fuel and it can eleiminate fuel cut. Fuel cut is a pain in the ass I still get it and my car is running totally safe. The SAFC only tricks your ECU into beliving it is getting less air into the motor and by tricking it the ECU automaticlly subtracts fuel out basically since you are not taking air away your just making it think it isnt there it takes fuel out to go along with the lesser amount of air it thinks it is seeing and the ratio ends up changed because it is realistically getting the same air as before but now less fuel. The SAFC will cause timing to change and the car be more able to cause knock which can be bad for your motor, My car has had no trouble and most people have no problems Just make sure you know what your doing thats all
Either way the biggest change with either is the air to fuel ratio from the factory they run like 9.8 which is INSANLY rich which means it is super safe but bad for power and gas milage, after tuning depending on your location and mods you will be around a 11.3 air\fuel which is just about optimal for 93 pump gas. at that point you will feel the power gain which is in most cases 20-30 AWHP and it makes a huge difference and you will also see your gas tank last llonger. Stock you get around 200 miles to a tank (best I ever got was 207) after you will average 250 miles to a tank and best I got after tuning with the SAFC was 300 on the highway.

It can void the warrenty and chances are it will if there is visual evidence. I just hide my SAFC when my car goes in and so far so good. The Re flash has no visual evidence I think if they plug into the obdII they can tell though.
SAFCII costs $310 new I paid $100 for mine off of a 3G eclipse owner... I actuall owned it origanally and sold it with my old 3G and then 3 years later bought it back from him.
I think Jestrtuning is in orlando they do drive outs to areas I lived in tampa for a while and met a few of those guys and chatted with them in clearwater which is tampa st. pete. area they do a drive out and get a list of people who they are going to tune and then set each person in time frames like an appoinment and they street tune your car.
So I would go on there website and see if they have anyone coming into tampa anytime soon if not I belive they do mail ins... so you can just mail in your ECU and tell them you exact mods and what boost you want in the end and they will tune your car to the proper specs and get you better gas milage and about 30AWHP to be gained
