whats up guys i'm having a little problem. First let me tell you whats done to my car. Ful Catback 2.5", hi flo cat, stock down pipe, Port and polished head, stock intake, and a boost controller set to about 16 pounds. when im driving and my rpm is at about 2 grand and just floor it takes alittle while for my car to build pressure which isn't normal and then when it gets to about 11 pounds the car starts jerkin back and forth like it wants to keep pullin but its being held back. I i drive to about 4 to 4 1/2 grand and step on the car fully pulls to 16 pounds. 4 gear it doesn the same and 5 gear it just sits at 11 pounds rockin back and forth. 1st and second get to about to 11 pounds and it feels like the hulk grabs my car and just pulls it back for a second. Sometimes if just sit there for a little bit in third and let the car jerk it then back fires and pulls extremely hard. If someone could help me, that would be awesome thankyou.

Most of what you're describing sounds like boost leaks. Do a test and tighten down on those clamps. Also, it may not be a bad idea to check your plugs, wires and also change the fuel filter if that hasn't been done in a while.

Good luck and let us know what you find.
