Default Tune without IAC??

Hi,

Strange question, but is it possible to remove the IAC from the tune?

I will be running 8 throttle bodies and don't want to see the IAC. Is it as simple as removing from tune and drilling holes in the butterflies to allow air to pass on idle? It's not a every day driver, and not chasing hp.


Thanks

Yes you can remove it. I just tuned 2 different engines with 8 throttle bodies and neither had IAC. Its easier with IAC in my opinion but you can tune them without it. Having them all synced correctly is probably the most important part of it.

Thanks. This will make life a lot easier.

So it's just the matter of drilling the right size holes in the butterfly's? Or adjust them so they don't fully close?
