Was there testing of this system w/o the BD programming?

Thank you!!
When comparing headers I did so with no tuner. And with tuner. Jba was the clear winner.

A tuner makes only a little difference when naturally aspirated as far as numbers. While it does in fact change driveability pretty dramatically.
