Default JDM EJ205 Swap Issue

Ill try to make this short and sweet. Hopefully somebody out there can give me a good idea as to if i need a tune or if i have a drive ability issue.

bought an 02 wrx with a popped engine for a steal of a deal

picked out my JDM EJ205 to swap and ordered one of these http://www.jdmflorida.com/index.php?...&product_id=79

I swapped everything
- intake manifold
- cam/crank gears
- cam/crank sensors
- knock sensor
- oil cooler, coolant crossover, intercooler brackets... etc (this part goes on and not important for driveability)

I got the engine in and the car started up and all went just fine until I began to get into boost. around 3,000RPM and 5-7PSI of boost, i get major hesitation until the engine feels to "catch" itself and then it builds up to 15PSI and pulls hard and fast.

I cannot figure out why i am having such issues with hesitation and cutting out.

I am worried that maybe this engine has a different compression ratio and i am leaning out? Any help would be great... im really at a loss of what this could be
