I don't usually succumb to the drug of modifications to perfectly fine new cars but the idea of plug and play anywhere from 40 to 60 horses is too tempting to ignore. But who do you trust with your new toy? It would be great if one of the magazines would buy 3 or 4 different tuners and do thorough comparisons. Suggestions would be Paul's, Justin's at VMP, Evolution's and I guess Ford racing. What opinions or experiences have owners on this forum had?
