I just found the computer in the fender well, That's the right one right? It has writing on it like its from a junk yard (good comp.) The truck runs fine I assume its the right one if its not the stock one. It doesn't look like its been apart, Is there any way to scan it and find out if its the stock one or the right one for the truck? Other mods are just K&N and 4'' straight pipe and a boost guage truck only hits 19#s everthing else is stock. Thanks Tom
