Need help with engine bogging problems after upgrading 06 GT

I have been looking through the forums and have yet to find and answer to my issue. I recently installed a CAI, delete plates, UDP, high flow CATs and x-pipe and axle back exhaust. All parts are from Steeda. I tunned the car with an SCT SF3 with the canned tunes that it shipped with from Steeda. My car really sings some of the time, but after it warms up and I stop for any length of time (red light, stop sign waiting on cars to pass, etc.) I get a serious bogging down of the engine. I can pull out slowly (to keep from going sideways) then floor it and the car makes a lot of noise but goes nowhere. After I go a few hundred feet everything seems fine again. Has anyone else experience this issue and if so, what solutions have you found. I am thinking of getting a Brenspeed tune to see if that helps, but I want to make sure I am spending my money wisely. Any help would be greatly appreciated.

I had a similar problem with my car and Doug at Bama adjusted the drive wire ,or throttle wire, in the tune. Now she screams.
Is your car auto or manual and do you turn off the
traction control when you get down on it ?

Use the tuner to turn off the traction control and then see what happens.

Its also quite possible the canned tune is out-of-sync with your modifications (common problem). Contact Steeda and see if they (since they are the supplier for all the goods) can help you with an updated tune as a download. Its likely you received the SCT standard, all OE assumed, tune - nothing wrong with what it is, but the CAI and other modifications change things.

Have you made adjustments to the tune yourself using the SCT?
+1 it may be just too many variables for the canned tune. If you have that much invested in mods it may be worth while to step up to a tune from Brennspeed or Bama.
All,

Thanks for the replies. I leve in north Alabama so I gave Doug at Bama a call. He is setting me up some tunes to see if that will solve the problem. If that doesn't work, I can drive down to his shop and have him Look at everything. Doug has been great over the phone and I would reccomend him to everyone. I will post here with the results of what we find.
