Default High idle on startup after turbo build?

Anyone in general have any ideas? Either it's vacuum leak or in the tune my guess is. After turbo build with mods in sig it was fine.. got it tuned, came home, now whenever I start the car it jumps to 2-2300 rpms and goes down to normal idle at 1000 or so. As if it had too much fuel to start and just ramped up quick. This makes me sketchy on cold starts..

Probably the tune, I had mine tuned after a Supercharger install and it does the same thing, momentarily surges to 2k or so then settles back to normal but in Texas we don't get as cold as Pa. Maybe a block heater install for cold weather starts ?

I mean the car will never be started when it's less than like.. 50 degrees outside anyways. It sits for the winter, I just wanted to make sure I have nothing to worry about that's all
