KADE-T hesitates at top end !! Help Please...

[dwaynedman]

Hey all, Maybe someone has had this problem and can help. I'll try to make this short. Just got done with the turbo on my KA , and am having a little trouble with idle quality, and hesitation at top end. The car will idle fine if I feather the gas for a couple seconds and let off. But if I throw a quick rev, and let off it wants to die. Also at top end starting at about 4500 r's it starts to hesitate a little and cut back all the way to redline. Here are a list of things I have done, and maybe someone can point something out.
