Is there a way to tell if my PCM has been tuned for the mods the previous owner did? I bought my 1996 Z28 SS from a used car dealer, and they gave me the stock cam in the Comp Cams box , which was installed by the previous owner who they say is a master mechanic / VA State Inspector .They said the previous owner had also installed under drive pulleys and 410 gears, but that's all they knew - They also gave me a Hypertech Tuner that was registered to my cars vin#. The car runs well , and the previous owner had the Redline set to 6800 RPM in the Hypertech memory. Thanks
