Default missing vacuum on "itb"/"turbo" motor

hi all

I have built up a motor with fuji throttle bodies and t28 turbo......I'm running hydra....all is great except.....ecru is not seeing vacuum quick enough when I get on the throttle....so I have a flat spot then it just pulls like ****....I think it is due to the small vacuum pipes on ITB'S not letting ecru see the changes quick enough.....I'm going to try Fujis vacuum canister as this collects all four feeds from ITB's....hopefully this will let ecru see what it wants...if not ideas please to solve this prob

cheers all

russ

What you need is to have your transient throttle tuned.
