Sorry if this is a stupid question, I feel I already know the answer but I've already been threw a motor so I wanna make sure. I have a 2000 lightning and I'm wanting to upgrade the maf to a 90mm. If I add the 90mm and use the pre loaded map will the truck run properly? The truck is currently stock ...

Okay, thank you very much!

I picked up a 2000 lightning, it's all stock and with the truck I was given a predator for it. I tried to upload and a message coming up that said that this tool is not licensed for use with this vehicle came over the screen. Is this programmer useless to me because it is married to another vehicle?
