High Idle after APS and 317 heads install After installing APS Twin turbo system and 317 heads I started the car up and it idles fine for a while.
When it idles for a while it starts climbing and sits around 2200 to 2400 RPM, if I shut it down and start it back up same thing.
Once it reaches operating temp, it will go to 2200 or 2400 RPM and sit there right away.
Do you think I forgot something or I need to tune for something?
I wanna drive the car to the tuneshop 19 miles away, but if I can't get it to idle normal then I'll just trailor it there.
Any Ideas guys?

So, you haven't driven it yet? Can you verify that the throttle blade isn't open at all. Do you have a scanner that you could check the throttle position? That sounds pretty basic. But, if that isn't it, like mentioned above it sounds like a vacuum leak.

PAGregSS you hit the nail on the head.
I tuned it rich to be safe and drove it all the way to the tuners shop like 20 miles away, upshifting like crazy to keep the RPMs down to not hit boost, and when I got there I opened the hood to show the tuner the work I had done and was explaining the High Idle issue and he looked around for like 10secs and said "Oh ****" lol, your throttle is a bit open... Thats when I realized I had removed the adjustment cover on the throttle cable and had reapplied it too tight. I cant believe I made such a big thing out of something that I could have taken a little more time to investigate and notice the throttle was not touching the set screw.
Oh well, if thats the only thing that goes wrong for me with this buildup I will be very lucky.
Thank you for your time and patience.
Your help is always appreciated.
