not a good night for the 6 first round runner up! I cooled it down to where I normally run at and dialed a 12.45 thinking I should be able to cover that. Car was on a 12.53! I'm missing about 3 tenths and 2 mph from normal!! Like I said, the only thing I changed was the plugs and added the spacers! WTF? Could the plugs make that big a difference?! The car had nothing in the higher RPM range. It felt as if it was just laying down. Any thoughts??
