Having loss of power at 50%< throttle

[WilbanksUSMC]

I am currently having issues with the car cutting power while under full throttle. I do not have any idling smoke, and when accelerating <50%, the car will hit red line, but it feels like it is struggling to get there. I have replaced the MAF and fuel lines, as well as my purge valve solenoid. My mods are just a HKS 3" intake and BOV w/ recirc. This is very urgent, I NGK's that i need to gap, going in the car this week. AP should be on the way soon too. But for now, does anyone have any idea what this might be? I thought maybe a really bad boost leak, but i don't see anything on the piping, nor i do i hear any whistling or whining while under boost.

Thanks

No internals? As soon as that ap gets to you I'd look at that fuel pressure. And you need a MAF cal for that 3 inch too I believe. I'd do more reading if I were you.

Put the OEM BPV back on, and put the stock intake back on. You're running dangerously lean with a larger-bore MAF housing.

Get an AP as quickly as you can, and tune for the mods you intend to put on. These are finicky motors, and you're risking serious damage right now.

Thanks guys, just trying to fix problems from the stealership. Bought it with the intake and bov kit -_-

Man buying a speed like that is dangerous!!! Think you should do a leak down test to make sure there's no motor problems. Hope all is well, good luck brother!
