Ok so since my boost starts at around 15-16psi in 2nd it's ok but when I hit 3rd it jumps up to like 18psi then in 4th it hits like 19psi causing it 3rd gear and 4th gear to be too lean. This really messes up the tune I think. Is there any way I can get it to hold 16-17psi in 2nd, 3rd, 4, and 5th gear? Any way to adjust the wastegate so it holds the same boost in all gears? What should I get for fuel if I wanna run 18-19psi just injectors or a return line and/or fuel pump too?
Post a datalog so everyone can see what you're talking about.
18-19psi is about where you want it.
Regardless of if you 'think' its lean, you should add fuel only in response to Knock. Adding up to 10%-15% Fuel is not out of the question.
2nd gear in my car breaks the tire loose at about 5K so its the quick rise in RPM pulls the boost back quickly to about 15psi from the initial 19psi spike. If you look at your RPM curve compared to your Boost curve you'd see the Boost lvl is very simliar at the same RPM. Since 2nd gear raises RPM so quickly it just looks like the boost level is different.

I don't have a laptop and my scangauges aren't working right now all I have is my wideband hooked up and sitting on the dash. In 3rd-4th gear my wideband reads up to 12.5ish. If I want more fuel should I get injectors?

lets try this again:
Use the DSP to datalog You don't need a laptop, the DSP will save a log internally.
DON'T waste money on injectors,,ADD FUEL WITH THE DSP, BUT ONLY IF THERE IS KNOCK!!!
can anyone please tell me how to? i don't have adobe so i can't download pdf files and in the predator manual there isn't anything to show about data logging

too lean in higher gears...
