I have a 99 Camaro with an unknown tune in it. The previous owner removed a lot of performance parts before he sold me the car. One issue I am having specifically is the trans pressure. He told me the car had a shift kit and it felt like it did. A few hundred miles later the trans went and during the rebuild we discovered the car had no shift kit in it. I can only assume the "hard shifts" were due to someone increasing the line pressure and prob lead to the trans failure. I rebuilt the trans with a Yank 3600 NOS Converter and transgo shift kit (set on performance street). Other than that the car is stock with a small Zex wet kit.

I have access to a HP tuner once I pay for the unlock. Can someone email me a tune? How does this work? I appreciate any help provided.

There were 3 different operating systems used in 99 and depending if the car came with 2.73 or 3.23 gears it could be one of these 5 possibilities.

just out of curiosity, what are the other variables to make the tunes different?

Comparing the files with the same gears, GM probably had complaints during the model year of vehicles with detonation and made changes to the vehicle cals to address the issue. The changes are mainly in the knock sensor settings, knock retard, and IAT timing modifier tables.

The cals with the different rear gear ratios have different speedometer, shift and converter lockup tables also.
