my first diy was tryin to do rotors and pads on my 99 lude, I couldn't budge the bolts. after wasting a day of my life I paid a local shop to do the work.
My second diy was tryin to do gauge overlays, nobody ever said you can't pull the needles out lol. so I did and ruined the gauge cluster. $200 later w/ a used cluster and the milage reset I was back where I started.
my 3rd diy went off w/o a hitch when I installed my aem v2 intake.
