there are a few ways of making sure you are in the ball park as far as jetting is concerned,,,make a pass at the 1320 mark click of the motor and coast on to the ruturn road and check a few plugs,dont make a pass and idle back to the pits you will not get accurate readings,,i also use a stand alone O2 system,you can record your data and save it,review it on a lap top and you can review the whole run,helps trouble shoot problems(fuel presure issues,jetting,power valves,) gmonde
