Robert, I just wanted to confirm with you. I to had removed all the air mass sensor and ran a flex pipe straight off the bottom of the air breather to the hole in the rear quarter panel. I saw a considerable amount of pickup. I also adjusted my air flow meter after the car warmed up to compensate if any. Coupled with 93 octane gas and the HV coil, I see a considerable pickup. I have take people riding in my car and they can't believe something else hasn't been do to it. One other note, if the air mass isn't working correctly, there will be a restriction of air and a possible richer mixture when running. If the valve doesn't open then it will pull hot air all the time off the exhaust manifold. John hervey http://www.specialtauto.com/
