i just bought my 1st gt a few weeks ago. its a 96 gt vert. the car is in great shape but that 215hp isnt gonna do it for me. i keep reading different things about "PI" and "NPI" 2v and 4v and frankly im a tad bit confused. i have no idea whats in my car or what route i should be taking to get more power. someone school me real quick
