Your missing the hose for your PCV. Look at your picture, top right side of valve cover, there is a shiny nipple coming out of the valve cover, should have a hose connected. I dont know if that will fix your issue...just a fyi

Usually you want to retune anytime you change parts that change how fuel, air enter the engine. Most of the time you can get away with not tuning with exhaust components. My best advise would be to read about what your interested in.

Evo's are well known not to play well with intake "pipes".
If this is the ONLY thing done to the car, I'm not surprised it runs like garbage. The car will need to get tuned and it MIGHT run alright. The general rule of thumb is to just run a filter with a stock intake snorkel. There was a GREAT writeup on intake filter comparisons done WITH dyno numbers. You can see how each affects each.
I would put the stock snorkel back on, and run the open filter. Then I would look to other mods if I wanted more power, since there are PLENTY of similarly priced mods you could do that would yield similar (or better) gains, and not have the same issues with driving.
But you will DEFINITELY want to get the car tuned.
For the new guys asking about tuning.
No. You don't need to get your car tuned after every little bolt on. But realistically you should. Most people will do their upgrades in stages, and tune then. So snag like a set of IC pipes, a filter, and an exhaust, with the supporting mods (fuel pump) and go get tuned. That way... it's affordable, and yields good safe results.
Contact a reputable tuner and talk about your goals. They're all plenty happy to help you have fun, and make them money.

Did you ever connect the PCV back into the intake pipe? Mine had a nipple to connect the PCV hose back into the intake

Maybe just a bit more bernoulli, and a little less newton and it'd be fine? Who knows... just run the stock snorkel.
