Well, it almost sounds to me like you may need one then (T/A or Chip). Is the H-pipe catted or non? It has always been told to me that when you start modding things, specially with air and fuel, you need to have the computer calibrated for it. 1. it will give you the most HP for your mods, 2. it will make sure the car runs properly for your setup. Good luck.
