The car idles fine until I rev it, revs to 2k are fine but if I rev it to 4k to 5k it will bog down and then stall out. Does anyone know what this problem is? The car throws no codes, and it will start right back up afterwards. I know it has a tune in it from when i bought it but i have no idea what the problem is. The car has a cold air intake, catless dp and full cat back.

Check that and the spill valve might need cleaned. That's a good place to start. I didn't get any codes with that issue but it would stumble and couldn't boost.

Full exhaust and no Hpfp?

I haven't checked yet, it most likely does as the car was once tracked. I'm trying to fix the car one problem at a time.

I will check that, thanks so much.
 
+1 for relief valve, get yourself a HPFP and at least an OTS tune with the AP that'll help.
Shouldn't cause a stall but clean MAF sensor, check spark plugs, and look for boost leaks.
 
If you don't check your hpfp and verify the internals are upgraded. You're gonna blow up then full part out or sell the scrap for $4.00 and hate mazda for the rest of your life
