Ok because of everyones input on the tweecer I think I am going to go ahead and purchase one. I know it will be rough to learn at first but i think once i get the hang of it my car should have a good tune. I just have one last question. I dont' have a laptop and don't plan on getting one but is it ok if i just bring my pc down in the garage and tune it or do you have to be driving the car around in order to get a tune. Thanks again for everyones input and help.
