Pete its a tuning issue. Wait till you get your Wideband. You will see why.

Alright, thanks guys. My guess is that the secondary injectors are just dumping too much fuel. The ecu is probably doing the same thing in the upper rpm's causing it to get more fuel than it needs.

I've had this exact same problem for 1 full year (ended up blowing my stock motor at only 8psi)
Now with my freshly built motor I bought a wideband and rechecked my old maps to realize I was running 9:1 AFRs at higher RPMS

'feels much better now at 12:1 AFRs

don't listen to people saying your turbo is too small until you see your AFRs !
