res and ubend delete on a grand prix gt

this is the cheapest mod u can do to your gp. ubend and res delete. this mod added slight throttle responce, slight mileage increace, and seemingly hp increace. my reasoning, is the car uses barley any effort to increace speed on the highway to make a pass. it doesnt need a downshift, a 10mph increace to pass on slight throttle preasure takes about 4-5 seconds and you will seem to fly by, havent matted it yet. after i got the part put on i tried an auto start from my remote at a local supermarket. it made me and the ricers parked next to me jump. the engine sound explains why this a great mod.
