Im thinking of getting a mild set of cams for my teg, 91 GS (B18B from a 94 LS) a set that can work with a stock valve train,but im not sure if I would need to get it tuned right away. I know tuning it would benefit my hp, but I cant think of any reason why I would have to do it right away. Would stock pistons defeat the purpose of cams? Should I just throw this idea out the window :bash and stick with other bolt on first? Yeah, probably . . . Anyways give me some input. Would a mild set of cams require ecu tuning or timing adjustment? Thanks.
