What do guys think is the best bang for your buck when it comes to tunning devices. There's so many ways you can go I don't know where to start. Some people say a (piggy back system with an injector in the intake tube) or a (harness/software to tap in the factory computer) or a ( custom chip ) or a (standalone system) I know that the standalone is probably the better way, but I talked to some people that have one and they still can't figure out how to use it properly, and the've had it for a while, it sounds complicated or i'm I just getting bum information. Any experienced knowledge would be appreciated.
