On the hard braking on loose gravel to get get the ABS pump to cycle, you should feel the brake pedal vibrate, and the DIC needs light up with "active handling engaged".
The pedal vibrating is just the ABS solenoid firing closed and you may get a ABS brakes message in the DIC, but if you don't get the active handle in the DIC, then do the hard braking on loose gravel again in a slight turn instead.
So again, ABS solenoids just restricts the fluid to a wheel or more to stop the wheel or two from skidding.
The ABS pump on the other hand, kicks in and uses the solenoids to apply the brakes to a wheel or more to get the car back straight without you instead.
So the solenoids, easy to power bleed through them, and its the air trapped in the ABS pump that you need to cycle to get it out of the pump instead. And again, the pump only cycles when the active handling kicks in to straight you back out, and the DIC will give you the notice with active handle from a skid that needed to straight the car back out forward again.

Drove the car to the tuner shop, no issues with the brakes, nice pedal throughout. CEL kept coming up, think due to the headers, at one point it was blinking, then steadied itself. I did find out that I lost ac, most likely due to me leaning on the ac hoses during the headers installation. Should get it back next Tuesday....

omg looks like you probably cursed a bunch on that job, best cheap solution to bleed brakes I have found is the motive brake bleeder. I just fill the master cylinder and pressurize the bottle with air, send about 1 master cylinder tank through each wheel at about 12psi no helper needed, fast enough to push air out quickly too. test with a $15 hydro tester to ensure less than 1% water and all is good

Brake gods just gave me a smirk and quietly left....
I looked for a motive pump with zero results, vacuum way works but only if you install the calipers the correct way. ....plenty of curse words were shouted, I basically teaching Spanish to the neighbors
It does worry me that my CEL was bliking even if it was for just a second or two.

Slow progress at the shop. Found out that I didn't route the front O2 extensions correctly and burned some wires on both sides. Also, I thought that the exhaust manifold had 3 missing bolts when I swapped to headers, and ordered a head stud kit to finish the job while at the shop; nope all 3 are broken below the head surface. The 2 against the firewall and one middle one on the right.
Now to remove the heads, which I didnt wan to mess with originally, just to remove those frakin studs
! Otherwise the supercharger install wouldn't be right....there goes the Tuesday deadline........
