SO HOW DO YOU REMEDY THIS STREET DRIVEN THING WITH 4 CORNER IDLE ? CLOSE DOWN THE BACK BUTTERFLIES? AND RUN YOUR IDLE ON THE FRONT ONLY? CAUSE THE BACK WORKS LIKE THE FRONT,AND WITH LOW VACUUM AND A REAR POWER VALVE, IT WILL OPEN AND CLOSE FOR THE STREET BUT WILL STARVE AT THE TRACK,,AND WITH A PLUG IN THE BACK, IT WILL GET MORE FUEL AND RUN RICH ON THE STREET
