Need some advise I own a 02 954 cali model[sm=smiley21.gif][sm=smiley21.gif]all stock, About to install a race slip on, pc3usb, velocity stacks, bmc race filter. I have removed the o2 sensor,Ialready have a bypass plug for it.Also have removed the fuel evap canister, do I plug the ports on the carbs were the lines were connected? Another question I have been reading the threads on the pair control valve, I have heard alot about the one were you just take the valve out and plug the holes, talking to the dyno shop they say they will do a pair mod for 100$$ but they call it a reverse they dont block off the pair valve ports on the valve cover, they say they reverse it, does anyone have any ideas on what that would mean? ALSO "ya so many questions" when you do the HTEV mod you should do the FLAPER mod also right? Has anyone lost thier low end by doing this mod?
