Dude...
1. Welcome
2. You don't need help "ASAP". Turn off your car, and relax.
3. A thread titled "need help asap" is completely useless as titles go. There may be experts in certain topics that when they see a title, they'd click on it, and there may be people who have no idea what they're talking about who just want to help someone and click the thread only to realize you're just wasting their time.
4. We need more information as to the specifics in order to help you.
A. What mods do you have?
B. Have you recently changed anything?
C. Which A/F Gauge is it?
D. What condition is the car in? Fluids, Plugs, Mileage, Maintenance, etc.

Haha yes its my first turbo car but I know this isn't right.
Mods:
Intake, exhaust no cat, peering fuel rail, cams, AEM A/F gauge, HKS EVC boost controller, apexi SAFC 2, Turbo xs utec
That about covers it.

the SAFC could be part of the issue, since you also have the UTEC. Two things doing the same thing. I would just ditch both of those and get a tactrix for the proper tuning

You need to do a boost leak test.
You can grab a tester somewhere off the web (siliconeintakes.com has them) or make one yourself (its super easy). Hook it up to the intake side of your turbo, and pressurize the system to 25psi. Fix any leaks you hear... and then spray soapy water on the joints to SEE if there are still leaks.
This is part of the diagnosis... you can't just expect the problem to fix itself, and you can't just wait for the ONE solution to present itself over the web.
If the ratio is spiking high (to 17ish) then the car is leaning out. But this can be caused by fuel getting pulled out because the computer sees too much and then the boost comes back on and there isn't enough.
