I just got my 93' RX7 but I need help. I need some suggetions for a fuel computer. What would you recomend? I'm hoping to get up to about 400whp but I need a more fuel. I really don't want to have to spend the money for a standalone so I would like to use piggyback fuel computer. Also, is it ok to stay with the stock injectors and fuel pump at 400whp or do I need to upgrade? Thanks a lot.
