Car bogging HELP!!!
Car bogging HELP!!! 
I have a 2000 Trans Am M6. Mods are pacesetter LT's, LS6 intake, Ported TB, Truck MAF. The car has been dyno tuned and the bogging problem cannot be found. EVERYTIME i shift after WOT it bogs and takes a second to come back and pull again. If you sit still and rev it up hard it will try to come back down to an idle but it cuts off like its flooding. If i am just cruising and come to a stop light and push in the clutch it tries to cut off too. I have cleaned the MAF, changed the injectors, tried a stock unported throttlebody and still does the EXACT same thing! ANY help is greatly appreciated. Thanks. It seems to be dumping fuel everytime i let out. The tune has been double and triple checked...maybe even more....I changed out injectors with the same types that were on the car.
O.k., this might sound like the pressure regulator might be jacked up. But before you go changing that, it also sounds like a vacumm leak. Same thing went on with mine when I got my bbk intake and TB. So what I did, I took of the intake manifold off and siliconed the **** out of the underbody and anywhere that looks like it should be sealed. not to mention, I also put a light coat of silicone on each of the intake ports(o-rings). Double check the back of the intake where the map sensor is and make sure its not loose, if so, silicone that **** too. This may sound like it looks ugly, but honestly, when you put it back together, you dont even see the silicon. a tube of silicone cost under $5 and to do this shouldnt take you more than two hours. Definately worth it. Needless to say, it cured mine right after that. Mine would die if I punched to the top of fourth gear and then let off. This scared the **** out of me cuz sometimes I would be turning ON my car at about 120mph after it had died! SCARY!! Hope this helps.
Ok so everytime I shift after hard throttle the car bogs down. These are the codes I am getting.

Verdad Gallardo ?????? I stumped dude~! Mess around with the hoses that go from the cylinder head to the throttle body, they may be set wrong. And one thing that just happened to us this weekend, we installed a tb on a bbk intake and with the bbk gasket, and the car was bogging. it turned out that the gasket had a hole plugged that the tb needed opened. so we cut around the gasket, put it back together and the problem went away.
