My car won't spool and is ticking? Urgent

[SPOOL_GSX]

I replaced my 0² sensor with a universal 4 wire and now when i start up my car it runs like crap, it doesn't hit boost ( even when i rev ), accelerates like it only has 5 HP, and a really really loud ticking is coming from the head-intake mani. area does anyone here have any suggestions at all? i need help any and all idea's are welcome, thankyou.

It sounds like you have a large exhaust leak. Make sure everything is tight. Also, when you start the car before it gets warm you can put your hand down there and feel for the exhaust leak. It will probably leave a black stain where its coming out at too.

Well now that you ,ention it (i didn't think that this mattered) i was running open cat for a while and then i just bolted up my 3"pipe to the cat, i ran like this b-4 without a problem, i don't see why this would couse this to happen, it's just a straight piece of pipe.

Well, Was the o2 sensor made specifically for your car? If not, I suggest changing it.
