cant decide which to get. trying to get faster times in quarter mile times and racing from rolling. got i/h/tp/e and was wondering to get either aem ems and tune, or the 4.77 gears. any suggestions please. thanks

 

people say the gears are the bang for the buck....
but since you have i/h/tp/e aem ems with tune you might get a good gain too....

 

aem with a good tune.

 

thanks.....
