No one should ever run a tune that wasnt applied to their exact setup.
For a base map, while you very gently drive it to the tuner, sure if every component in the system is the same or damn similar(intake manifold, header, exhaust, literally anything else). But absolutely not all-out at a track. I wouldnt even drive it over 5k on a tune not made for my car.
Your tune was designed to get the most out of your car with your mod configuration.
If homie is salty, it was he who took the risk here.
