i have about... 700 dollars im stuck between getting a loc for the rear or a tune... If i get my tune it will be from Lido due to all the gret things i've heard and ill have 300 left over... but i dont know what id do withthat left over either! Also on Lido's site it says when your at a dead stop and put the pedal to the floor it will spin the tires just from a tune. Ok.. well i want that.. but i dont want a right wheel peel only..so im thinking of just getting a loc first .. and install.. hopefully for 500 or less and wait a couple weeks for enough money for my tunner.. but i want the power and to peel out! Does a loc give you any extra "oomph" in your but dyno? thanks in advanced.!
