The car would not run again without this missing table. No tuner would be able to install the missing table. If this happened to you, the car needed to be towed to the dealer and then have the ECM re-flashed, then re-install the supercharger tune yourself. NOT FUN! To prevent the potential problem, it was just a precaution to do the ECM update at the dealer before I did the supercharger install. It was not a wide spread issue but it did happen to some forum members here. BTW - Not all dealer's service departments would agree to do this re-flash without a "reason" they could understand :(. They certainly would not do it under warranty. I had to pay for it. Cheap insurance.
I drove the car a few weeks after the re-flash before installing the supercharger. I did notice the reduction in afterfiring at that time. It was just a side effect.

Do you have any more info on this? Seeing as how the ECM is used in other vehicles I wonder what GM did with the early operating systems in the camaro....or if it was an issue with a handheld tuner?
