Loss of power at exactly 7.5k RPMS
As the title states..
So I had issues with my idle, which I recently finally fixed. Solution? New plugs, wires, BHR Ignition, AEM Intake + new MAF. Finally got the car to stop slowly dipping under 700 rpms which would cause the car to shake pretty hard.
So now that it idles correctly, go figure something else. I took the car on a spirited drive the other day and notice then when WOT the car would climb strong until exactly 7500RPMS hesitate for a second, then continue fairly strong.. maybe not 100% its hard to tell.
I do currently have a slight exhaust leak between my header and catless midpipe which I tried fixing with a new crush gasket but apparently need 2. So I have another in the mail, not sure if this could be a cause.
Current status:
81500 Miles
Passed compression test
P0420 for running catless, only CEL
Stock flash, also cleared VRAM
Cleaned new MAF just incase
Rechecked plug tightness, wires, and BHR ground.
Regardless of gear, I just find it strange it happens at EXACTLY 7.5k. Any input to possible causes or any additional info I could provide?

Water Foul
That's the first thing that came to my mind as well. And, the tach on the dash reads high compared to the OBDII data in my car, so he could actually be losing power at 7250 instead of 7500.
