As far as the tune goes. ( Disconnect the battery first!) Just go to the upper left hand (passenger side) of your engine bay, and the computer will be sitting right behind the passenger strut tower. Take the 2 10MM bolts out and slowly pull it out the space it's in. then loosen the 2 10MM nuts on the plastic case that surrounds it, and put that aside. There is a little cover on the top side of the computer. take that off and you will see the chip in there ( it's blue in color). Now you have to be careful, and push down the tabs on each side of the factory tune and it will pop out. Then all you do once you have the new tune from PCMforless, is plug the stock tune onto the exposed prongs of the chip you received, and then clip it back into the computer. Don't force these things on either. there is only one way they can go so make sure they are oriented correctly and then snap then into place. Then put it all back together. Wish I had pictures for you.

Thanks for all of your help guys! This is my first time messing with Computer Cars. I have built plenty of Double Pumper cars in the past but never one of these guys!

Basically you just wire in 12v to the correct wire.. I tapped the fuse/relay box for 12v when IGN key is switched on.. Google or search here for diagrams .. It's easy and makes for better idle ,tuning and milage ... I went back to delco afs75's be sure to use only them.. All other brands rich/lean thresholds are off and cause issues..
