i just got an 87 performance tune from justin at vmp wow this tune is incredible really makes the car scream. but i did notice that when i ahve the car at WOT and take off from going slow going into second gear(its an auto by the way) the car has a nice firm shift then i hear a screech sound or a chirp now i believe its the tires but i am not sure because from my seat it sounds like its coming freom in front of me with the windows open. so i was curious if anyone had any experience with this. i belive its just wheel chirp but just wanted to double check to be safe. thanks guys
