My car is a 2019 Bullitt (which has the GT350 intake manifold). I actually sent my factory TB to Soler and they ported it to 91MM and no tuning was required.
Yes, I mailed them my factory TB, they ported it and mailed it back to me. Take a look here.
I would skip the throttle body honestly. The stock TB isn't nearly of a restriction as some other items that can be done. Porting your manifold, exhaust, e85 tune among a few others would be great starting points to get a few more hp out of the car. Just the tune alone, depending on whether you're a 10 speed or 6 will be the best bang for buck out there. If you have any questions about anything, feel free to reach out anytime. lethalperformance.com
Pick a good reputable tuner and have them remotely tune your car. I recommend adding all bolt on performance mods that you want before you do, whether that’s headers, x or h pipe, axle back exhaust, cold air intake kit and throttle body or any combination of the aforementioned. That way when the tuner writes your tune, you can gain maximum benefit from all mods, especially E85 if you’re open to that.
The device is just used as a tool to upload a custom tune or to data log.
As Stephen said. You wouldn't see much gains with a throttlebody. Your money would go a longer way with investing in a E85 tune, ported manifold, cold air intake, or headers.
