I need a new PCM for my '01 Z28 m6. GMPartsdirect has the 0411 for vette cheaper than the 4896 that's specific to my car. Which is better please??? I don't mind the price difference but I want the best, car is stock and will get serious bolt ons in the future. Software tuned regularly. I thought all LS1B pcms are the same but I hear the 411 talked about often...?Click image for larger version.  Name: Screenshot_2018-01-23-01-47-39.png  Views: 231  Size: 140.6 KB  ID: 21793Click image for larger version.  Name: Screenshot_2018-01-23-01-46-40.png  Views: 293  Size: 143.0 KB  ID: 21794
