Here's my dilemma. I purchased my car used from a delaer, and it had a predator tune in the computer, but there was no predator with the car. I even contacted the previous owner(w/my mafia ties), and he said he put it in the trunk....blah blah blah, I exhausted every measure, and I can't get it. So when I had the car retuned, I took it to a local shop and they programmed a revolution chip, so the tune in the computer was overridden. I just ordered a KB with a chip, and KB will be programming the chip according to my mods. Can I just put the SCT chip from KB in place of the Revolution chip that is running my car right now??? I will get the car retuned professionally very soon, but I will wanna drive it for a week or so until I can get it in. I really don't wanna have to buy a predator and a stock tune just so I can get it back to stock. AAAAAAAHHHHHHHHHHHHH
