Car sputtering/cutting out under throttle...?

I have an 03 wrx w/ 170,000 miles on it. I replaced the stock wore out motor w/ a fresher 02 motor. The motor has about 100,000 miles on it now. I have upgraded my exhaust to an all catless system....down pipe, up pipe all the way back out. It has a stage 2 tune as well.

Well last week coming home from a fishing trip my car started actin like a bitch! Under throttle much more than half it will sputter out....kinda like its not getting enough fuel. SO i put some fuel systems cleaner in my tank w/ a full tank of gas. Its about half empty now and the problem has gotten a little better. But what do you guys/girls think i should do now? Have you had similar issues?

I would like to upgrade my injectors...just not now $$$. I also have a new walboro fuel pump but havent installed it cause i want to do injectors at the same time. Thanks in advance

Might just be a bad tank of gas. Keep topping it off with the pee-water you call premium when you can. Pick up a few bottles of B12 Chemtool (po-man's seafoam).

Why are you talking about further modding a car (completely pointless mods on top of that) when you have problem you haven't even diagnosed yet?

Why do you give a stupid response when nothing in your original post said that was the case.

It's not the injectors. There are 2 dozen things that will causes this before your injectors fail.
