I will post some dyno charts and info with the exhaust when we are finalize the exhaust.
Do you guys have any plans to make a downpipe in the near future? Nice work so far as expected.

Both charts are form the same vehicle, dyno runs were made back to back to keep conditions and all other variables as close as posible. The tuner exhuast was installed during those runs.
I don't think you are being intentionally evasive but you didn't really answer the key question (because you say the exhaust was installed "during those runs") Do both the before and after runs have the exhaust installed, or just the after runs?

BOTH before and after runs have the exhaust. We used the valet switch to change between stock and modified.

Okay, I'm I the only one finding this dyno hard to read?
I see torque numbers on the left, but no HP numbers, so no way to see the HP curve?
Am I missing something?

I know this may sound like a silly question, but can the dyno software do an equivalent of integration in calculus?

That way, you know not just the peak, but the total area under the curve, which to me is more important.
