Currently i have gutted my cats and i made a dual glasspack setup on the rear. Now my question on the dennis chip, what am i goign to have to change when i purchase this chip, ive heard that i have to get colder plugs and i have to get a 180 degree t-stat. But will this chip give me any performance gains like in ponies and if it will how many???????? thanks for the help guys i really appreciate the replys.
