Default please help just bought my first stang!

i just bought my first mustang it is a 89 gt with a 5.0 and a t5. i am having a little problem. when i accelerate with half or three quarters of throttle it pulls nicely but the second i put it all the way the the floor if feels like it bogs out. also in the morning when it is cold it hesitates really bad but only for about a half mile then it good . but the full throttle problem always happens. the car has headers, catted H pipe, flowmaster cat back and a under hood cold air intake, all that stuff was on it when i bought the car and it has been doing it since i bought it, there is no check engine light on. if any body can help me i would greatly sppreciate it. thank you brian.

Does it have a MAF after the air cleaner?
