Good point from twin3037 as well. You really need to go to a better shop even if it costs you more money. One thing I have learned over the years is to not cut any corners and look to save money by going to a cheaper shop. If you are going to modify your car do it right and spend the money to have it done right. You can have all of the parts in place but if you dont have somebody that can tune the car appropriately it doesnt matter. Tuning is everything!!!
