Ok my father recieves auto electric mags and pamphlets with info about auto electrics. i read in one of them the other day, that people consistantly over look there ground wires when doing upgrades. As i read on, the article claimed you can unleash (up to) 10hp just by puting a good ground wire kit on your car. I repeat, up to 10hp. So i put a monster cable ground kit on the car, and wow there is a huge differ in throttle response and idle. i used 4 guage braded wire.
