Thanks guys for giving me hints!

Update:

I feel a lil dumb right now--> Since i swapped my fuel pump+fpr, more fuel was gettint to the engine.... I was running under 10 AFR. I knew I was running very rich, but I didn't know it would make the engine to run like crap when boosting...

i had a small boost leak too!

Now everything is tuned properly and runs gr8!

Thanks for helping me out!
