How not to tune!!

This guy has been tuning a long long time. Apparently, he hasn't gotten any better, as ALL the crap I see coming out of that shop is very similar. This one is particularily horrible! It had so much idle air, combined with an unbelievably high amount of startup airflow, that it zeroed the IAC!! KOEO, the IAC went to zero.

Now, most of you know I'm not one to talk smack about other tuners, just out of respect. But this guy is totally different. He's a real piece of work.
Drum roll please. This tune is brought to you by none other than the great Jeff Creech of Carolina Auto Masters! FWIW, I've retuned literally dozens of cars from him over the years. They're ALL terrible, but this one kinda takes the cake.
