I really haven't had to use it yet though because I didn't have any idle or shift issues on the ones that I've tuned.

My engine is 502 mag efi, that engine iac is so slow that it not help nothing. Late idle timing make engine idle slow, so you put more basic idle air in and engine idle good. When on gear, advanced timing with little bit more air gives more power to idle on gear

We got it tuned great this past weekend. I was using a 32P bravo. I am putting on smaller pulley on blower and putting on the MAX5 34P prop for some speed tuning etc.
