Intake manifold tract airflow distribution...

[Alky V6]

It had very little. I would say 100 miles or less mainly highway and some of that was "alky on" time. After the 32psi passes it came home and the owner ordered a new turbo. I put it on and he went for a short test drive at 18-19psi. after that he drove it to our hot rod garage and my buddy upgraded the rear brakes. He drove it a few blocks at the same boost and the owner took it back home 20miles or less. Drove it back to the "shop" and said "I want a little more power..." After that my buddy and I tore it all down in the car to do heads, cam, intake and some cosmetic upgrades. Then the trans decided enough is enough .

Was the EGR operational on this car?

Yes.

Then... and now.

Yes.

That certainly helps to muck things up a little with a lot of steady throttle driving.
