Before I start, let me just apologize because I am sure I will get a few veterans yelling at me for asking questions that have already been answered in other threads, but Ive actually spent the last few days trying to figure this out and I'm just digging a deeper and deeper hole for myself. Im just plain lost....
I just bought an 05 WRX and for a first mod (besides better tires.. and maybe a driving lesson) I was thinking about reflashing the ECU. I am not planning on going crazy with engine mods, but I'd like to do the basics ie change the exuast to a fully turbo back system. After reading a ton of threads it seems like the best way to go is to purchase one of these all inclusive stage 1 upgrades. The thing is I don't want to do it all at once. Id like to eventually get to a point where my car is turbo-back. Should I buy uppipe downpipe and catback exaust first and purchase the reflash second or the other way around. I was thinking about going with Vishu stage 0 first and then either buying the stage 1 upgrade or adding the turboback seperately after. However, I don't want to spend money to reflash the computer every time I add something.
This is where I get really confused... A reflash means just that I take it to a tuner and they spend some time playing with the ECU right? I know nothing about tuning, but I'd like to be able to change to different pre-programmed maps like if the weather changes (it snows alot where I live). Do you ahve to purchase something seperately to allow you to do that like the Cobb AP or ECUTEC? If someone could in plain language describe the appropriate engine management approach (options prices etc that would be great) for a newbie such as myself that doesn't that would be sweet. Im not looking to put 350hp in the car, I just want an every day driver that is legal and takes advantage of WRX's full potential. Once again, I apologize because these questions are all over the forums but I haven't found one long detailed thread that I can understand and follow logically (they are just all over the place from Cobb AP and UTEC and ECUTEC etc etc.) Please help!!Thanks !!
