Also, I would like to mention that we do not recommend the GT350 throttle bodies due to known issues with surging and stalling - these concerns are not something that can/will be addressed in the tune file.
We can write the initial tune for the GT350 throttle body, but if you experience an issue that is thought to be related to the GT350 throttle body, we will recommend installing the stock throttle body, and using an adapter plate to pair the stock throttle body with the GT350 intake manifold:

A $49.99 custom tune update will need to be purchased to have the file updated for the stock throttle body.
The stock throttle body will offer more desirable drivability, and there is not a significant power difference between the stock and GT350 TBs.
