pros. faster acceleration, quicker throttle responce,more power
cons......... the only issue i have had is that i had to get used to take off at a slightly higer rpm ( very slight increase) i have stalled the car 2 times in traffic but honestly got used to the difference very quick. i was worried about a loss of torque but i realy havent notniced any loss so there are no cons to this just a slight change in driving style
