Can we live without the IAB?

[Mike_W]

It seems to be just a choke device. I was having high idle bet. shifts and when i'd come to a stop, so I took it off. Then I would have trouble keeping it running when cold(like choke) until warm(then it ran fine). The other day I read a post describing how to fix this, so I put the stupid thing back on and the high idle went away... somewhat, it drops rpm when coming to a stop (good), but between gears it stays at whatever rpm i'm shifting instead of dropping. I think i'll take it back off, but will this affect the dyno tune & chip i'm getting soon?
