SC pulley
Is the SC pulley difficult to install? NO, 1/2 hour or less with patience, a lil skill and right tools. Is a tune definitely needed with one?[/QUOTE] YES, for sure. Car will most likely run lean with a SC pulley and NO tune. I know mine did and Jerry/Jake fixed that for me.
Really? Jake told me I would be fine with out a tune? No doubting you, just wondering why we got different answers. I ran the SC pulley for about a month with no tune.
