WOW,
You tell people here that you DON'T need to upgrade the stock injectors on a stock turbo but you did.... hmmmm
.
WOW,
I upgraded my injectors because my plans for the near future include a 3037 turbo (i.e. 450 whp).
Better luck next time with trying to read my mind.
But seriously, if you want to know the reasons behind my upgrade rationale, don't just assume they are based upon some mysterious evil agenda, because they aren't. Just ask first next time.

Hmm I thought HKS only made 2.5" downpipes? Oh yeah B&B responsed and said I could send back the defective downpipe to them for inspection. They said they will put it on a rig to test, does that mean they will put it on an actual evo?
So what your saying is that just reflashing would be as good as putting in a afc2 and mbc? Will I need a mbc with the flash? I mean if I was to continute to mod my car will I need the afc2 to tune the car even more because I think I cant configure the flash without resending it in.
Ok if I do a reflash, which companies do you evo owners recommend I choose?

You don't need head studs...unless you're running higher (e.g. >24psi) boost pressures - and you won't be.
You don't need just about anything in Ang Wen Yan's post.
If you want more power and likewise want to keep it discreet, here's what you should consider...
3" turbo-back exhaust setup. The larger cat and cat-back alone are not enough to get everything you can from the exhaust. Whether you do it half-way or all the way should make no difference to the dealer, and since you cannot hide any of it, you may as well do ALL of it. I've not heard of a dealer attempting to negate warranty work on the count of an exhaust system.
The 255lph fuel pump is worthwhile, inexpensive, and fixes the only weak link in the fueling system. With this, your fueling system is good for a hypothetical 350whp or so.
Don't expect much from the aftermarket intake. The factory intake is not a restriction, and there are cars running 11sec E.T.'s with it.
The safc and MBC are ok if you like fiddling with it, but adhere to what Corey said above...without a means of recalibrating certain pertinent issues in the ECU, you will be limited. A reflash is invisible to the dealer, but not to the dyno.
Finally, another 'invisible' mod that is worthwhile would be HKS 264 cams. The car will idle like stock, but can pick up quite a bit of power with proper tuning (e.g. reflash).

I'm using a comprehensive tuning system, so I won't be able to comment to the extent of some others on the finer details of reflashes...
If you get a flash, you still may need an mbc if the flash removes the factory boost limitations but does not otherwise control boost. You'll have to check into that. Persons who can better answer this question can be found at Dynoflash and Turbotrix.
An safc allows one to have control over wide open throttle (WOT) fuel trim. It can be useful to the extent that the WOT fuel curve is off. This is likely an unecessary item if the car is dyno tuned with a flash, or if you get a mail order flash and do not have access to a dyno.
By no means is this the most extravagant route to a better state of tune, but it will allow you to get much more from bolt-on hardware.

An SAFC also has a partial throttle setting that will work at a user defined throttle percentage, so you can increase your fuel economy with that provided you have a load bearing dyno and a capable operator to tune it.
