Here is the video of it idling after the tune. It still doesn't idle very well when I first start it. Since I had the tune done would I maybe still need to drill the TB? It seems to be fine for the most part when it's warmed up. Or is this normal for a cam? http://media.putfile.com/Trans-am-228230-can-tuned

 

I wouldn't drill the TB, talk to your tuner.

 

Yeah...talk to the tuner. The purpose of drilling the tb is to bring the IAC counts down if they're too high. The rest of the idle controls are in the PCM. Either way, you need to scan the car to understand what's happening.

 

drilling the throttle body is like amputating the leg for a broken ankle. not the right way to do it.

you don't have a very big cam...you should be able to straighten it out in the tune.

 

What software did they use to tune it, should be able to adjust your idle when tuning it as long as it is good software, HP tuner, LS1 edit etc.
